You're not making any sense. Mil
ton Friedman was not "the one pushing it." He was one of many people who thought tax credits for low income earners was a good idea. You think Milton Friedman invented the EITC?
Plenty of economists believed in tax credits giving to poor people. Andrew Mellon, Warren Harding's Treasury Secretary, one of the most important people in American economics history, and someone who influenced Friedman and supply-side economics in general, proposed and implemented a form of an earned income tax credit 50 years earlier. It's not irrelevant just because you don't want to acknowledge it.
Milton Freidman OPPOSED the EITC when it became law in 1975. You're giving all the credit to someone who didn't even support the law.
Friedman supported the NIT. NIT =/= EITC. Friedman's idea of a negative income tax was one that would compound with higher income earned...it was supposed to be an incentive to get people to earn more money and motivate people who didn't work to start working. And it was specifically designed to replace the welfare state and replace it with vouchers.
The EITC is just a refundable tax credit to help lower income earners with keep their heads above water. It's not a partisan ideological concoction. Trying to claim it as a neoliberal Friedmanite success is not accurate.
