George Washington law professor and economist Neil H. Buchanan explains in plain English what Mick Mulvaney meant when he attempted to justify President Trump’s budget proposal that would cut programs that help America’s most vulnerable, such as Meals on Wheels and subsidized school lunches for poor children. As Buchanan explains, Mulvaney’s explanation is based on a false notion that better-off people gain as much utility from each dollar as worse-off people receive from the same amount.
