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 ... 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 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. In recent decades, by contrast, only very affluent families ... have received such large raises. Yes, the upper-middle class has done better than the middle class or the poor, but the huge gaps are between the super-rich and everyone else. The basic problem is that most families used to receive something approaching their fair share of economic growth, and they don't anymore.
