Why the promise of a wealthier future for the next generation is failing
For decades, the social contract assumed each generation would be more prosperous than the last. Today, that cycle is breaking. Younger cohorts are accumulating significantly less wealth than their parents did at the same age, threatening not just individual financial security, but the stability of the global consumer economy.
The economic landscape has shifted fundamentally over the last half-century. In the 1970s, the ratio of private wealth to national income in the UK stood at 3:1; today, that figure has doubled to 6:1. This surge in wealth, primarily driven by soaring property values and robust pension growth, has not been distributed equally. While older generations benefited from these asset booms, younger cohorts—particularly those born in the 1980s—have faced stagnant income growth and declining homeownership rates compared to all birth cohorts since the 1930s.
This divergence is not merely a matter of personal savings. In the United States, millennials currently hold only 3% of national wealth, whereas baby boomers held 27% at a comparable stage in their lives. Across three decades, the total share of wealth owned by individuals under 40 has plummeted from 13% to under 7%. This creates a profound reversal of the historical trend where each generation could expect higher disposable income than the last. For those born in the 1970s, real income growth over a 25-year period is projected to be less than a quarter, a sharp decline from the doubling of income experienced by those born in the 1940s and 1950s.
The implications extend beyond personal hardship to the broader economy. Younger families between 25 and 40 have historically served as the primary engine of consumer spending. As this demographic struggles with lower wealth and stagnant earnings, businesses risk losing their most vital market. While some argue that inheritances will eventually bridge this gap, increased longevity means these transfers occur much later in life, potentially reducing social mobility and cementing a divide where living standards are increasingly tied to parental circumstances rather than individual productivity.
