Inheritance is quietly sorting Korea's young into two classes
Among Koreans in their twenties and thirties the widest gaps are no longer between occupations but between those whose families can supply a housing deposit and those whose cannot.
For most of the past half-century Korea told a coherent story about advancement: study hard, place well in the entrance examination, join a good employer, and the rest follows. The story described something real, and its collapse among people born after about 1990 is one of the more consequential social facts of the decade. The reason is arithmetic. Earned income grows more slowly than the assets it is meant to buy, and the difference is made up by families.
The wealth statistics carry the argument. Statistics Korea’s annual household finance and welfare survey, conducted with the central bank and the tax authorities, breaks net worth down by the age of the household head, and dispersion within the under-forty group has widened faster than the gap between age groups. The bottom fifth of young households holds net assets that are negligible or negative once education and deposit loans are counted; the top fifth holds assets an order of magnitude larger. What separates them is rarely salary. Entry-level pay at large Korean employers is compressed, and the difference between a conglomerate salary and a mid-sized firm’s does not compound quickly enough to explain a tenfold spread in net worth before forty.
Housing does. Apartment prices in Seoul roughly doubled over the second half of the 2010s and into the early 2020s before correcting, while real wage growth ran in low single digits. A young household that entered the market in 2015 and one that waited did not merely experience different returns; they entered different asset classes. Because the standard Korean rental contract requires a lump-sum jeonse deposit rather than monthly rent, even renting at the good end of the market demands a capital sum, so the family transfer determines not only ownership but the quality of tenancy.
Those transfers are large and increasingly documented. National Tax Service statistics on declared gifts show a marked rise over the past decade in both the number and the value of gifts to people in their twenties and thirties, with real estate a growing share. Declared gifts are a floor rather than an estimate: undeclared cash, a parent servicing a deposit loan and free accommodation in the family home appear nowhere in the tax data. Regulators’ periodic audits of apartment purchases by buyers under thirty exist precisely because the gap between young buyers’ incomes and their purchases is visible in the administrative record.
The consequence is a within-generation stratification that the older Korean vocabulary of class does not capture well. Two graduates of the same university, hired in the same year at comparable salaries, will diverge permanently depending on whether one received a deposit. The one who did services a smaller loan on an appreciating asset; the other pays monthly rent that yields nothing and saves against a target that moves faster than the saving. Over fifteen years the gap becomes unbridgeable by any plausible difference in diligence. Surveys of young Koreans’ attitudes toward mobility have recorded a steady decline in the belief that hard work determines outcomes, and it is declining because the arithmetic changed, not because the young became cynical.
The policy instruments available are all awkward. Inheritance and gift taxation in Korea is nominally among the heaviest in the OECD at the top rates, yet the effective incidence on ordinary family transfers is modest. Housing supply in the metropolitan area is constrained by land, by regulation and by the preferences of existing owners, who vote. Deposit-loan support for young buyers, the most popular instrument, adds to demand in a supply-constrained market and can raise the very prices it is meant to help people meet.
None of this is unique to Korea; a rising ratio of inherited wealth to national income has been documented across advanced economies. What is distinctive is the speed, and that it happened to a society that had, within living memory, been genuinely fluid — which is why the loss registers as a broken promise rather than as the ordinary condition of a rich country.
