Uh, Reaganomics is just another name for supply-side economics, which is an economic school of thought. I mentioned an economic theory in a discussion that involved economic theories. So silly of me.
You sound very confused. I can tell you're just making shyt up on the fly and googling stuff frantically in order to appear more learned than you really are. "Right wing implementation of a left wing idea?"

A lot of the New Deal policies did exclude blacks. That makes them racist, not right wing.
Keynesian economics being toward the left end of the political spectrum is not dumb. It's basic political knowledge than any poly sci undergrad student knows. We're not just talking about Keynesian fiscal policy though. Strong labor unions, higher taxes at the top end, the G. I. bill, a robust social safety net, etc. and basically approaching economic policy as building by securing the middle class as this country did from the 30's through the 70's, were not necessarily Keynesian, but it's easy to connect them because Keynesian theory calls for the public sector to pick up the slack during periods of stagnant growth, and Keynesian was the standard until the late 70's and 80's when the Chicago school stuff gained prominence.
To summarize Keynesian fiscal policy at a very, very basic policy level, it's increasing spending and cutting taxes and using monetary stimulus during periods of low growth, then decreasing spending and raising taxes during periods of steady growth. That's what the country did until the Reagan years.
Reagan was right wing relative to the previous 50 years of economic policy. That's my point. I don't even know what you're attempting to argue or what point you're trying to make. I don't disagree with thr rest of what you said.

What the fukk are you talking about? Reagan did not increase peoples' standard of living. I guess you're one of those people who swallow the bullshyt propaganda that Reagan was responsible for the economic growth of the 80's when anyone with any sense knows it was because of Paul Volcker expanding the money supply and slashing rates after contracting it on the 70's recession years.
This isn't about Reagan though. It's about the new status quo that was introduced under Reagan that has maintained prominence to this day: laissez-faire neoliberalism, deregulation, union-busting, privatization, free trade, top marginal rates in the 20-40% range instead of the 70-90% range.
The white standard of living has dropped. Real wages, savings, and standard of living has declined for the past 35 yeard and it's run concurrently with exploding income inequality. You think white people in middle America haven't seen their wages cut and jobs disappear?
But wait, that's due to "white liberal ideologues"?
Get a clue dude. You obviously don't know what you're talking about and think you're equipped to debate stuff out of your depth by googling anecdotes you don't fully understand.
