I have been crunching some data recently on the historical gap between real GDP growth and wages/income of households. Some of this work will be forthcoming in an article due later this month, so keep an eye out for it. Some of it is post-dating the article submission. Here is an example of the latter. The following chart plots index of real GDP from 1Q 1959 through 1Q 2019 against the index of real disposable income per capita. Both indices are set at 100 at 1959 average.
There are 5 distinct periods over which growth in real GDP moved further and further away from growth in real disposable income. All are associated with monetary accommodation periods post-recessions, and all are associated with increasing post-recession financialization of the U.S. economy and financial or real estate asset booms.
Interestingly, the current rate of acceleration in the gap between economic growth and disposable income growth is... underwhelming. It pales in comparison to what was witnessed in the 1980s, 1990s and 2000s. To see this, consider the chart showing this gap by itself:
Despite our commonly-expressed public, media and analysts' perceptions of the declining share of economic growth going to disposable personal incomes being a new (current) phenomena, the reality of historical data paints a different picture. Most of declines in the share of economic activity accruing to wages, bonuses and investment and retirement incomes have taken place in previous decades, with the ratio of real GDP to real disposable income being relatively stable from the start of 2013 on. Prior to that rate of the decline in the relative share of disposable income has been less sharp from 1999 through 2012, when compared against all other decades.
The debasement of real incomes has been a steady and historical continuous process over the last 60 years.
