Our Broken Economy, in One Simple Chart

David Leonhardt | New York Times | August 7, 2017

Many Americans can’t remember anything other than an economy with skyrocketing inequality, in which living standards for most Americans are stagnating and the rich are pulling away. It feels inevitable. But it’s not. A well-known team of inequality researchers — Thomas Piketty, Emmanuel Saez and Gabriel Zucman — has been getting some attention recently for a chart it produced. It shows the change in income between 1980 and 2014 for every point on the distribution, and it neatly summarizes the recent soaring of inequality.

The line on the chart (which we have recreated as the red line above) resembles a classic hockey-stick graph. It’s mostly flat and close to zero, before spiking upward at the end. That spike shows that the very affluent, and only the very affluent, have received significant raises in recent decades. This line captures the rise in inequality better than any other chart or simple summary that I’ve seen. So I went to the economists with a request: Could they produce versions of their chart for years before 1980, to capture the income trends following World War II? 

The message is straightforward. Only a few decades ago, the middle class and the poor weren’t just receiving healthy raises. Their take-home pay was rising even more rapidly, in percentage terms, than the pay of the rich...The post-inflation, after-tax raises that were typical for the middle class during the pre-1980 period — about 2 percent a year — translate into rapid gains in living standards. At that rate, a household’s income almost doubles every 34 years. (The economists used 34-year windows to stay consistent with their original chart, which covered 1980 through 2014.)...
