Income inequality is finally getting the attention it deserves. New York Mayor Bill de Blasio ignited the imagination of the city running against it, but his focus is even larger.
“This inequality problem bedevils the entire country,” he said in his inaugural address. “It is not just a moral outrage, it is a horrible constraint on economic growth and on giving people the security they need to tackle problems.”
But what caused the problem?
Progressives usually trace it back to policy from Republican administrations, but it seems to go back much further than anyone realizes. The following graph is from the Federal Reserve of St Louis:
The line in red charts the Gini index (right scale), a measure of inequality. A Gini of 0.0 is perfect income equality — everyone earns the same pay, and a Gini of 1.0 is perfect inequality or one person earns everything. It’s a statistical and technical measure that allows easy comparisons across time and nations. It’s plotted with workforce participation in blue (left scale) as a percentage of people over 16 years old who have a job.
Note that both lines take off in 1968, the year that the Baby Boomers, born 1947-1964, entered the workforce in large numbers. While the Gini numbers don’t go back much further, we do know that from 1948-1968 the workforce participation rate never exceeded 60 percent. In the 1970s and 1980s the workforce was young and hungry, looking for work wherever they could find it.
While we can trace the growth of income inequality back to 1968, the reason may not be obvious. But as more people are looking for jobs the competition for every opening is more intense, and those with jobs can be replaced easily. One strong possibility is that an expanding workforce placed downward pressure on wages for working people constantly over 30 years.
Since 2000, however, the workforce participation rate has fallen. The St Louis Federal Reserve has published a paper predicting the workforce participation rate will be under 60 percent by the early 2020s as Baby Boomers start to retire. Yet there is still not upward pressure on wages – at least not yet. Rapid productivity gains made many jobs redundant, and even before the wave of retirement started hitting some people gave up looking for work – going to school, staying home to raise the kids, or simply living in terrible poverty.
This is an important point because even at today’s 63 percent workforce participation the total number of jobs needed above the post WWI 60 percent is 4.6 million jobs in a workforce of over 153 million. It would mean an unemployment rate of under 4 percent.
The difference becomes even more stark when you look across nations. Below is a chart of some of the largest economies in the world in 2012, both developed and developing.

Note that developed nations generally have lower workforce participation rates, many of them 60 percent or lower. And generally there is a correlation between a lower workforce participation and a lower Gini index, meaning that fewer workers chasing after the jobs that are available results in high wages for working people.
In other words, it appears that income inequality is largely a function of supply and demand for workers, and that in a highly productive developed economy there are only enough jobs to reasonably employ around 60 percent of the available workers without downward pressure on wages and rising income inequality.
That conclusion is certainly disturbing, but it is logical. Most of the jobs in the developed world are not manual labor but are highly productive specialty skills with computers and machines. There is only so much demand for the incredible amount any given worker can produce no matter how voracious consumers are. That implies that there is a reasonable cap on how many people can have such jobs at a decent, living wage.
What then is the solution? We are about to find out what happens to a nation where much of the population is living off of Social Security and savings. The simple fact may be that with only so much work to go around either the hours per worker should be reduced or a greater reliance on public assistance of some kind is natural.
No matter what, the roots of income inequality go back much further than people realize. Some of the problem may correct itself as the Baby Boomers age, but the implications for why that could work out are vast and challenge the basis of our entire economic system.
