“The broad-based income inequality of the ‘80s and much of the ‘90s, when a shortage of skilled labor drove up white-collar wages, gave way to the more cartoonish income inequality of the 21st century, defined by the outsized income share enjoyed by the top one percent. Nowadays you can experience economic resentment all the way up to the 99th percentile. According to Berkeley economist Emmanuel Saez, incomes for the one percent rose 27 percent during the economic recovery that began in 2009, while incomes for the bottom 99 percent rose only about 4 percent. (That’s through 2014, the last year for which data are available.) That 99 percent includes most of the country’s college graduates. Maybe they’re becoming an angry bourgeoisie. ”
