Inequality has been growing for several decades. It’s well past the obscene level. New York Times columnist David Leonhardt reports that, since 1980, average net income of the bottom 90% has grown only about one-fourth the rate of the GDP growth. For the top 2% to 9%, average income growth has roughly matched the rate of GDP growth. For the top .01% to 1%, average income growth has been about twice the rate of GDP growth. For the top .01%, average income growth has averaged about five times the rate of GDP growth. It was in this environment that Republicans enacted a tax overhaul designed primarily to benefit the rich and especially the superrich. This country needs, not just a “wealth tax” or a 70% marginal rate on incomes over a million dollars per year, but a tax system that’s revenue-neutral or positive and much more progressive across the board.
