Earlier this month, Representative Alexandria Ocasio-Cortez, a freshman Democrat from the Bronx who identifies as democratic socialist, created a stir by calling for raising federal tax rates on incomes over $10 million to 70 percent.

“You look at our tax rates back in the sixties and when you have a progressive tax rate system, your tax rate, let’s say from zero to $75,000, may be 10 percent or 15 percent, etc.,” she told Anderson Cooper on CBS’s 60 Minutes. “But once you get to the tippy-tops — on your 10 millionth dollar — sometimes you see tax rates as high as 60 or 70 percent. That doesn’t mean all $10 million are taxed at an extremely high rate, but it means that as you climb up this ladder, you should be contributing more.”

Cooper called Ocasio-Cortez’s proposal a “radical agenda.” Not surprisingly, Republicans greeted AOC’s interview with outrage (and willful misrepresentation of the plan’s distributional effects).
