ALL men are created equal, but they do not stay that way for long. That is one message of a report this month by the OECD, a club of 35 mostly rich democracies. Many studies show how income gaps have evolved over time or between countries. The OECD’s report looks instead at how inequality evolves with age.
As people build their careers, or don’t, their incomes tend to diverge. This inequality peaks when a generation reaches its late 50s. But it tends to fall thereafter, as people draw redistributive public pensions and quit the rat race, a contest that tends to give more unto every one that hath. Old age, the OECD notes, is a “leveller”.
Will it remain so? Retirement, after all, flattens incomes not by redistributing from rich seniors to poor, but by transferring money to old people from younger, working taxpayers. There will be fewer of them around in the future for every retired person, reducing the role of redistributive public pensions.
One logical response to the diminishing number of workers per pensioner is to raise the retirement age. But that will exacerbate old-age inequality, if mildly. Longer careers will give richer workers more time to compound their advantages. And when retirement eventually arrives, the poor, who die earlier, will have less time to enjoy their pensions.
