Inequality in labor and capital income

[T]he upper 10 percent of the labor income distribution generally receives 25-30 percent of total labour income, whereas the top 10 percent of the capital income distribution always owns more than 50 percent of all wealth (and in some societies as much as 90 percent). Even more strikingly, perhaps, the bottom 50 percent of the wage distribution always receives a significant share of total labor income (generally between one-quarter and one-third, or approximately as much as the top 10 percent), whereas the bottom 50 percent of the wealth distribution owns nothing at all, or almost nothing (always less than 10 percent and generally less than 5 percent of total wealth, or one-tenth as much as the wealthiest 10 percent). Inequalities with respect to labor usually seem mild, moderate, and almost reasonable (to the extent that inequality can be reasonable – this point should not be overstated). In comparison, inequalities with respect to capital are always extreme.

Hatgioannides, Karanassou and Sala seek to take account of these profound changes in the distribution of income and wealth. They do so by dividing the average income tax rate of a particular slice of the US population by the percentage of national income commanded by that same group and by their share of wealth.

They then look at whether by this measure – the fiscal inequality coefficient – the US tax system has become more or less progressive over time. The findings show quite clearly that it has become less progressive.

In terms of income, the poorest 99% of the US population paid nine times as much income tax as the richest 1%, both when John F Kennedy was president in the early 1960s and when Ronald Reagan beat Jimmy Carter in the 1980 race for the White House. By 2014, they paid 21 times as much.

Similarly, the bottom 99.9% in the US paid 28 times as much tax as the elite 0.1% in the early 1960s and the early 1980s, but by 2014 they were paying 76 times as much.

The same trend applies – although it is not pronounced – when income tax is divided by the share of wealth. The bottom 99% paid 22 times as much income tax as the wealthiest 1% in 1980 but were paying 47 times as much in 2014. The bottom 99.9% paid 58 times as much income tax as the top 0.1% before the onset of Reaganomics; by 2014 they were paying 175 times as much. The paper’s research does not extend to Britain, although given that the distribution of income and wealth has also been tilted in favour of the rich and the very rich, a similar picture would almost certainly emerge.

As the authors note, since 1980, economic policy making has been dominated by the idea that deregulation, less generous welfare and tax cuts will stimulate higher investment, higher productivity, higher growth and higher living standards for all. None of this has occurred and, what’s more, the social mobility in the decades after the second world war has been thrown into reverse. The great American dream – the notion that anybody can strike it rich – is dead.
