Your argument is sound, but I would go back farther than that. Reagan, with his libertarian economist, "Milton Friedman", brought neoliberalism ( trickle down 'supply side' economics ) to fore. In this spirit, he repealed the fairness doctrine, which as a doctrine that specified that TV news programs had to give equal time to both parties. If someone on the left was on TV for 5 minutes, they had to give someone on the right a chance to rebut for 5 minutes, etc. Repealing this doctrine, inspired by neoliberal ideas from Milton Friedman, the Chicago and Austrian schools of economics, allowed the right to take over AM radio, because now they didn't have to have any one challenging their point of view, so it was 'hate - the -left' for years, 24/7 then came cable, Fox news, then the birth of the Tea party and now Trump. It's called 'neoliberalism', a doctrine that says anything the gov can do, they think private can do better, which is why they are trying to privatize the post office, social security, etc. Neoliberalism has done more to destroy America than any other concept. The term is hardly ever used, but look it up on Wikipedia, it has nothing to do with the left. It's alt - right territory now, and it's morphed into right wing nationalist populism.
