Summary

The household problems of South Korea, Japan, and China may appear different on the surface, but their structures are quite similar. In all three countries, explaining sluggish consumption simply as a matter of 'psychological contraction' misses the core issue. Households do not close their wallets because of vague pessimism; they rationally reduce spending because of stagnation or regression in real purchasing power, high housing costs, debt repayment burdens, unstable employment, and care and education expenses. The difference lies in which cost exerts the strongest pressure. In South Korea, housing costs and household debt are the key constraints; in Japan, long-term real wage stagnation and the non-regular employment structure; in China, the property market adjustment, employment instability, low social security, and high precautionary savings.

The conclusion of this report is clear. To revive consumption in all three countries, interest rate cuts or campaigns alone are insufficient. First, household disposable income must be directly increased. Second, housing must be treated as living infrastructure, not as an investment asset. Third, the quality of employment—especially stability, wage growth, and social insurance coverage—must be improved over quantity. Fourth, reproduction costs such as care, education, healthcare, and old-age security must be socialized. In Marxist terms, the problem is not 'psychology' but the cost of labor power reproduction and the distribution structure.

1. Problem Setting: Why 'Consumer Sentiment' Explanations Are Insufficient

Mainstream discourse often attributes sluggish consumption to 'psychology.' But households do not consume based on abstract emotions. Wages, interest, monthly rent, jeonse deposits, mortgage loans, education costs, medical costs, old-age insecurity, and employment stability combine to determine consumption capacity. In other words, consumption is a function of class and material conditions before it is a psychological variable.

Viewing the three countries through a common framework reveals four core issues:

  1. Real wages and real disposable income: Even if nominal wages rise, if prices rise faster, the consumption base weakens.
  2. Housing costs and asset market structure: Home prices, rents, deposits, and interest costs eat into living expenses.
  3. Defensive nature of debt and savings: High debt replaces consumption with repayment; weak welfare turns savings into insurance.
  4. Labor market dualism and social reproduction costs: Peripheral groups—non-regular workers, youth, women, migrant workers, peasants—cut consumption first.

From this perspective, the difference among South Korea, Japan, and China is a matter of 'who is more insecure and by how much,' and the commonality is that 'households self-insure against future insecurity out of their own pockets.'

2. Comparative Framework at a Glance

Item South Korea Japan China
Core of Consumption Sluggishness High housing costs and household debt suppressing consumption Long-term real wage stagnation, non-regular/low-wage structure Property market adjustment, employment instability, low social security leading to expanded precautionary savings
Real Wages/Real Income Very weak real income recovery recently Cumulative real hourly wage decline 2019–2023; household real income still weak in 2025 Real income increased in 2024 but consumer sentiment and employment confidence weak
Housing Cost Problem High PIR, concentration in capital area; jeonse and loan structure expands debt Burden in large cities exists, but national average burden milder than Korea/China Obsession with homeownership and property asset instability causes consumption contraction
Debt/Savings Household debt among highest in OECD, interest rate sensitive Household debt lower than Korea but pressured by low wages and aging High savings propensity; strong savings for housing, education, and medical care
Policy Priorities Lower housing costs + stabilize household debt + income support for lower classes Institutionalize wage increases + improve non-regular employment + support care and housing Direct household support + expand welfare + decommodify real estate

3. South Korea: Income Holds Up but Consumption Is Squeezed; Housing Costs and Debt Grip Households

3.1 Consumption and Household Livelihoods

According to Statistics Korea's Q2 2025 Household Income and Expenditure Survey, the average monthly income per household was 5,065,000 won, up 2.1% year-on-year, but real income was 0.0%. During the same period, average monthly consumption expenditure was 2,836,000 won, increasing by only 0.8%. The numbers speak for themselves: even if nominal income rises, after accounting for inflation and fixed expenses, it is effectively stagnant.

South Korea's consumption weakness is structural rather than simply cyclical. Even if income increases slightly, the increase is tied first to interest, principal and interest repayments, jeonse and monthly rent, and housing-related expenditures rather than flowing into daily consumption. Both the Bank of Korea and the OECD point to high household debt as a key risk constraining consumption.

3.2 Real Wages and Disposable Income

Even if the number of employed persons is maintained in South Korea, consumption cannot easily revive if real wages do not rise broadly and stably. In particular, youth, non-regular workers, the self-employed, platform workers, and households in provincial areas feel income pressure more acutely than the average. The fact that average statistics hold up does not mean the popular consumption base is solid.

Moreover, South Korea still has blind spots in social insurance and welfare. This forces households to bear future insecurity privately, so even when additional income is generated, it goes toward precautionary savings or debt repayment rather than consumption.

3.3 Housing Cost Burden: Capital Area Concentration and Assetized Housing

The core bottleneck in South Korea is housing. According to the Ministry of Land, Infrastructure and Transport's "2024 Housing Survey," the national PIR for homeowner households was 6.3 times, and 8.7 times in the capital area. For youth homeowner households, PIR was 6.0 times; for tenant households, RIR was 16.0%. National development indicators generally consider a rent-to-income ratio exceeding 20% as an excessive burden. The national average RIR is below that threshold, but for youth, low-income, and small tenant households in the capital area, the burden appears much higher.

The problem is not just the price level. South Korea has a unique finance-housing system combining jeonse and mortgage loans. The procurement of jeonse deposits, mortgage loans, credit loans, and parental asset transfers intertwine, turning housing access into financial access. This structure transforms housing from a living necessity into a leveraged asset, simultaneously inflating household debt and suffocating consumption.

According to Korean social indicators data, the homeownership rate was 57.3% in 2021, and tenant households accounted for 39.0%. The gap between multi-home owners and youth without housing is also large. This explains why, under the same inflation, class experience diverges extremely: the upper class sustains itself through asset prices, while the lower class reduces consumption due to housing costs.

3.4 Household Debt and Consumption Suppression

In OECD household debt indicators, South Korea's ratio of household debt to net disposable income was among the highest in the OECD as of 2022. The Bank of Korea reported that household credit balance at the end of Q2 2025 stood at 1,952.8 trillion won. The absolute scale is large and sensitive to interest rates and real estate prices.

In such an economy, higher interest rates immediately hit consumption. Conversely, lowering interest rates again channels funds into housing and credit. In other words, South Korea has a structure where monetary policy alone cannot simultaneously manage consumption and financial stability. Slow consumption is not a psychological problem but a problem of excessive concentration of household balance sheets on housing.

3.5 Assessment for South Korea

The core issue in South Korea is not that "wages rise a little," but that housing costs and debt absorb the wage increases. Therefore, reviving consumption requires not only income policy and financial stability policy but also housing system reform.

4. Japan: Long-Term Real Wage Stagnation and Non-Regular Structure Break the Back of Consumption

4.1 Consumption Recovery Is Weak and Uneven

Japan has less household debt burden than South Korea and relatively lower bubble pressure in the housing market. Nevertheless, consumption does not recover strongly. The reason is long-term wage stagnation and employment dualism.

According to the Statistics Bureau of Japan's 2025 Annual Household Survey, the average monthly consumption expenditure for households with two or more persons was 314,001 yen, up 4.6% nominally and 0.9% in real terms year-on-year. The average monthly income for worker households was 653,901 yen, up 2.8% nominally but down 0.9% in real terms. That is, even if consumption expenditure picks up slightly, the income base remains fragile.

Japan's consumption showed signs of a rebound after COVID-19, driven by recovery in service spending, inbound tourism, and expectations of some wage increases, but it is difficult to see this as a stable recovery that a broad range of households can feel.

4.2 Real Wages: The Present Tense of the 'Lost 30 Years'

The OECD Employment Outlook 2024 states that Japan's real hourly wage fell cumulatively by 2% from Q4 2019 to Q4 2023. It also notes that real wages declined for 25 consecutive months through April 2024. Although nominal wage increases in the 2024 Shunto were higher, it takes time for these to fully spread across the labor market, and transmission is weaker for small and medium enterprises (SMEs) and non-regular workers.

Japan's fundamental problem is not just prices. Over the long term, wage suppression, expansion of non-regular employment, rigidity of the seniority system, and the large-firm/SME gap have accumulated, weakening the labor income share. If real wages do not rise, consumption is structurally suppressed.

4.3 Labor Market Dualism and Reproduction Costs

The OECD Japan 2024 Economic Survey points out that non-regular employment is concentrated among women, and the wage gap between regular and non-regular workers is large. It also analyzes that women bear a heavy burden of unpaid care work and that balancing childbirth/childrearing and career continuity is difficult. This directly links to consumption issues. Precarious labor and the private burden of care prevent households from increasing long-term spending.

In other words, it is not simply that 'wages are low' in Japan; rather, a labor and family system that makes it difficult to plan a stable life course weakens consumption. Delayed marriage and childbirth, the rise of single-person households, regional decline, and aging all appear as individual phenomena, but they are actually connected to the problem that the costs of household reproduction are not sufficiently guaranteed socially.

4.4 Housing Costs and Debt

At the national average level, Japan does not see housing costs and household debt overwhelming the macroeconomy as in South Korea. Household debt as a share of disposable income is also lower than Korea's by OECD standards. However, in the Tokyo metropolitan area and large cities, housing access costs remain high, and monthly rent burdens are heavy for low-wage, non-regular households. Japan's characteristic is not a 'massive debt explosion' but rather that low wages and unstable employment make housing burdens relatively heavier.

In other words, even at the same rent level, if real income stagnates, the burden ratio increases. Japan's housing problem should be seen not as an explosion of financialization like Korea's, but as a problem of insufficient public rental housing and housing benefits amid low wages, aging, and changing household structures.

4.5 Assessment for Japan

The biggest barrier to consumption in Japan is not the asset market but real wage stagnation and labor market segmentation. Therefore, the key to consumption recovery is not temporary corporate wage hike announcements, but the institutionalization of wage increases covering SMEs, non-regular workers, women, and youth, along with expansion of social services.

5. China: Why Consumption Is Weak Despite Rising Real Income – The Role of Real Estate, Employment, Welfare, and Savings Structure

5.1 Current State of Consumption and Income

According to China's National Bureau of Statistics (NBS), per capita disposable income nationwide in 2024 was 41,314 yuan, a real increase of 5.1%. Per capita consumption expenditure was 28,227 yuan, also a real increase of 5.1%. Urban residents' per capita consumption expenditure was 34,557 yuan, rural 19,280 yuan. Among consumption expenditures, housing-related spending was 6,263 yuan, accounting for 22.2% of the total.

On the surface, Chinese households are still growing. But stopping here would be a misjudgment. The core issue in China is not the average growth rate, but why consumption is weak relative to the growth rate, and why households prefer saving.

5.2 More Important Than Consumer Sentiment: Weakening Employment and Income Confidence

The People's Bank of China's (PBOC) Q2 2024 Urban Depositor Survey shows the psychology of Chinese households not as 'psychology' per se, but as a reflection of material conditions. In this survey, 61.5% of respondents said they would save more, while only 25.1% said they would spend more. The employment sentiment index was 33.8 and the income confidence index was 45.6, both below 50. This means not a lack of optimism, but weak employment and income prospects.

Chinese households are not consuming less simply because they are pessimistic. They defend themselves through savings because the labor market outlook is weak, social security is insufficient, real estate asset values are shaky, and the burden of education, healthcare, and old-age care is heavy.

5.3 The Link Between Real Estate Adjustment and Consumption Contraction

For a long time, China's growth system tied real estate to local government finance, household assets, construction investment, and bank loans all at once. When this system shakes, it not only hurts the construction industry but also damages household asset perception and future income expectations. The IMF's 2024 Article IV Consultation notes that China's economy is holding up amid continued weakness in the real estate sector, but that private consumption growth could weaken in 2025. The IMF suggested that supporting domestic demand and structural reforms are needed to mitigate the vicious cycle of property adjustment, low expectations, and weak demand.

China's particularity is that consumption can weaken even if housing prices do not keep rising as in Korea. Because real estate was a core household asset, price stagnation or decline simultaneously weakens the 'wealth effect' and amplifies future insecurity.

5.4 A Bigger Problem Than Real Wages: Insufficient Redistribution and Social Security

China still shows growth rates at a middle-income level, but households' share has not grown quickly enough. This is why the low share of household consumption in GDP has long been noted. Especially peasant-workers, youth, platform workers, and informal urban service workers are exposed to employment instability and vulnerability in social insurance. The hukou system creates regional disparities in welfare access and privatizes the burden of education, healthcare, and housing.

Under these conditions, even if income increases, the propensity to consume is unlikely to rise. Households use their own savings to prepare for risks that the state does not guarantee. That is, China's high savings are not cultural but the result of institutional insecurity.

5.5 Assessment for China

China's consumption weakness is not a matter of 'people not spending money,' but a problem that income and safety nets are not sufficiently transferred to households. Therefore, the solution is not large-scale supply expansion or re-stimulating real estate, but direct household transfers, expansion of public rental housing, local government fiscal restructuring, and strengthening social security.

6. Common Structure of the Three Countries: Consumption Is Not Emotion but the Result of Distribution and Reproduction

When the three countries are placed side by side, the following common patterns emerge.

6.1 Commonality 1: Vulnerability of Real Purchasing Power

  • South Korea: Real income recovery is weak; increased income is absorbed by interest and housing costs.
  • Japan: Long-term real wage stagnation and non-regular low-wage structure erode the consumption base.
  • China: Official real income increases, but due to weakened employment and income confidence and insufficient welfare, the conversion to consumption is weak.

In all three countries, households lack confidence in current or future real purchasing power.

6.2 Commonality 2: Housing Has Become Part of an Accumulation Regime Rather Than a Living Necessity

  • South Korea: Financialization of housing is the strongest.
  • China: Real estate was a key link between local government finance and household assets.
  • Japan: Relatively milder, but the low-wage structure causes housing cost burdens to press on labor reproduction.

The more housing is commodified and assetized, the more households must allocate wages and debt for shelter, and accordingly other consumption contracts.

6.3 Commonality 3: Precautionary Savings and Debt Repayment Replace Consumption

  • South Korea: Debt repayment crowds out consumption.
  • Japan: Households spend conservatively amid income stagnation.
  • China: Savings preference is strong due to welfare gaps and employment insecurity.

The forms differ, but the result is the same. Households become risk management units that privately manage insecurity rather than consumption entities that sustain domestic demand.

6.4 Commonality 4: Class Structure and Reproduction Costs Are Central

The layers where consumption weakens first are generally similar: youth, women, non-regular workers, low-income earners, the self-employed, provincial residents, migrant workers, and peasants. These groups have fewer assets, lower wage bargaining power, and weaker access to welfare. Therefore, explaining consumption contraction through the 'average household' obscures reality.

7. Marxist Interpretation: It Is Not 'Consumer Sentiment' but a Crisis of Labor Power Reproduction

Simply put, for a worker to be able to report to work tomorrow, housing, food, education, care, healthcare, and old-age security must be maintained. This is labor power reproduction. In all three countries, a large portion of these reproduction costs are offloaded onto wages and within families.

  • In South Korea, housing, education, and debt repayment erode wages.
  • In Japan, low wages, non-regular employment, and gendered care burden households.
  • In China, households bear more of the risks of housing, education, healthcare, and old-age than the state does.

Under these conditions, the demand to increase consumption is essentially contradictory. Households prioritize survival over consumption within unstable reproduction conditions. Therefore, consumption weakness is not an irrational psychological phenomenon but a rational defensive behavior born from wage suppression, assetization, and welfare deficits.

Furthermore, the capital accumulation strategies of all three countries have pressured households.

  • South Korea: Asset accumulation dependent on real estate and credit.
  • Japan: Prioritization of corporate profitability recovery, delayed wage pass-through.
  • China: Investment and real estate-led growth, insufficient household transfers.

In other words, reviving consumption requires not 'policies to make people feel better' but policies that change the distribution structure and reproduction system.

8. Policy Solutions: Let's Separate Short-Term Stabilization from Structural Reform

8.1 South Korea

Short-Term Stabilization

  1. Expand cash transfers, especially for the bottom 50% of households

Considering inflation and interest burdens, targeted support for low-income groups, youth, single-parent families, and the elderly has a higher consumption multiplier than universal campaigns.

  1. Relieve principal and interest burdens for variable-rate and vulnerable borrowers

Since interest rate cuts alone carry a high risk of re-heating asset markets, targeted debt restructuring and support for switching to fixed rates for vulnerable borrowers are necessary.

  1. Reduce jeonse/monthly rent and deposit burdens

Rent subsidies for youth and non-homeowner households, interest subsidies for deposit loans, and immediate expansion of public rental housing supply.

  1. Buffer essential living costs for energy, transportation, and necessities

This has a large effect in defending real income and also supports short-term consumption.

Structural Reform

  1. Reduce the financial commodification of housing

Curb multi-home and speculative holdings, recapture land profits, and significantly expand public rental and social housing.

  1. Reform the capital area housing cost structure

Not just supply, but also decentralize jobs, education, and healthcare from the capital area. Otherwise, even supply expansion is absorbed by price assetization.

  1. Combine household debt restraint with improving wage-led distribution

Debt regulation alone is insufficient. The labor income share must be raised and social insurance coverage expanded.

  1. Socialize care and education

Reducing the burden of private education and family care is necessary for disposable income to translate into consumption and improved quality of life.

8.2 Japan

Short-Term Stabilization

  1. Compensate real income for low- and middle-income groups

Tax rebates or cash transfers in response to energy and food price rises.

  1. Conditionalize support for SME wage increases

Link subsidies not simply to wage hikes but to regular employment conversion, normalization of subcontracting prices, and expanded social insurance enrollment.

  1. Strengthen social security for non-regular and part-time workers

Direct effect on groups with high consumption propensity.

Structural Reform

  1. Realize equal pay for equal work

Without reducing the regular/non-regular dual structure, the consumption base cannot be restored.

  1. Reform the seniority system, long working hours, and gendered division of labor

Reducing women's career interruption and low-wage traps broadens the household income base.

  1. Combine family policy and housing policy

Without simultaneously strengthening childcare, care, and housing support, it is difficult to concurrently achieve childbirth, household formation, and domestic demand recovery.

  1. Strengthen public services and regional living infrastructure

Responding to aging and regional decline is also a consumption policy. People can only consume locally if they can live locally.

8.3 China

Short-Term Stabilization

  1. Expand direct household transfers

Cash support and social benefits for youth unemployment, low-income groups, peasant-workers, families with children, and the elderly.

  1. Convert unsold and distressed projects into public rental housing

The aim should be housing stability, not bailing out developers.

  1. Prioritize livelihood stability over local government consumption stimulus

Support for medical care, education, unemployment, and child-rearing costs is more sustainable than one-off consumption coupons.

  1. Employment stability measures

Link social insurance for youth, service industry, and platform workers; expand public employment programs.

Structural Reform

  1. Reduce the real estate growth model

Reduce dependence on land finance and the pre-sale, leveraged structure.

  1. Expand social security and reform the hukou system

Only when urban migrant workers have real access to education, healthcare, and housing welfare will their consumption propensity rise.

  1. Increase the household income share

Raise the share of wages and transfer income to rebalance from investment-centered to household-centered growth.

  1. Equalize public services nationwide

As long as regional and class disparities remain large, precautionary savings will stay high.

9. Principles Common to All Three Countries

  1. Transfer directly to households

Indirect support via corporations, real estate, or financial institutions does not effectively revive consumption.

  1. Lower housing costs

One of the most powerful policies for domestic demand recovery is reducing housing costs, equivalent to raising real wages.

  1. Reinforce non-regular workers, youth, women, and migrant workers first

These groups have the highest marginal propensity to consume and are currently under the greatest pressure.

  1. Remove the causes of debt or precautionary savings

Debt repayment pressure in South Korea, the need for savings in China, and low-wage instability in Japan are the cores.

  1. Treat consumption as an outcome; find the cause in income, housing, and welfare

Consumption promotion campaigns alone cannot change the structure.

10. Conclusion

The sluggish household consumption in South Korea, Japan, and China wears different faces, but it is commonly the result of a system in which households bear too many reproduction costs. South Korea's consumption is suppressed by housing costs and household debt; Japan's by long-term real wage stagnation and non-regular structure; China's by property adjustment, welfare deficits, and employment instability.

Thus, the solution is also clear: directly raise income, lower housing costs, stabilize employment, and expand welfare. In Marxist terms, domestic demand recovery is not a psychological campaign but a matter of socializing the costs of labor power reproduction and correcting the distribution structure. Before telling people to "consume," we must first make it possible for them to live.
