This RAND study finds that the median income in the U.S. would be $42,000 higher than it is today if the income gains over the last forty years hadn’t gone mostly to the top 10 percent.
And a college-educated worker making $70,000 today would be earning roughly $120,000 if the income distribution was the same as it was in 1975 — before the “rising tide” began lifting only yachts.
The reasons we are seeing the rich taking an ever-larger share of the economic pie? Tax cuts and loopholes for the wealthy, bail-outs and monopoly profits for corporations, attacks on unionized workers and higher tax burdens for the lower and middle classes.
