There’s more to inequality than education
In a blog post yesterday, Paul Krugman again noted that the growth in income inequality is not all about education.
He pointed to two different charts to illustrate: one showing the growth of the top 1 percent relative to other income groups and a second with wage growth by education levels. Since the two charts had different scales, it was hard to see just how out of whack the education-explains-inequality story really is.
Below is a chart that combines the two series in one chart, showing that the top 1 percent has outpaced, by a very wide margin, not just those with less formal education, but college grads as well. And this gap between the growth of the top 1 percent and the rest is much larger than the growth gap between education levels.
This is not to say that education is not important. The chart also shows that those with a college (or post-secondary) degree have outpaced others. But it’s also clear that this trend only explains a small part of the broader inequality story.
(Note: The top 1 percent line shows the growth in average after-tax incomes for this group, via the CBO, data from Figure 2. The education lines show the growth in wages for all workers, via EPI’s State of Working America data on wage and compensation trends by education. Both are inflation adjusted.)
