There was a time when asking who benefits from economic growth didn’t seem urgent, because income was rising steadily for just about everyone. Since the 1970s, however, the link between overall growth and individual incomes seems to have been broken for many Americans. On one side, wages have stagnated for many; adjusted for inflation, the median male worker earns less now than he did in 1979. On the other side, some have seen their incomes grow much faster than the income of the nation as a whole. Thus C.E.O.s at the largest companies now make 270 times as much as the average worker, up from 27 times as much in 1980.

A similar disconnect between overall growth and individual experience seems to lie behind the public’s lack of enthusiasm for the current state of the economy and its disdain for the 2017 tax cut. G.D.P. numbers have been good in recent quarters, but much of the growth has gone to soaring corporate profits, while median real wages have gone nowhere.

But how do facts like these fit into the overall story of economic growth? To answer this question, we need “distributional national accounts” that track how growth is allocated among different segments of the population.

Producing such accounts is hard but not impossible. In fact, the economists Thomas Piketty, Emmanuel Saez and Gabriel Zucman have already produced estimated accounts with considerable detail over the past half century. The main message is one of growth going disproportionately to the top and not shared with the bottom half of the population, but there are also some surprises in the other direction. For example, the middle class, while still lagging, has done better than some common measures indicated thanks to fringe benefits.
