reagans terms redefined the rebuplican agenda from the time before him. Starve the beast, the two santas, supply side exconomics, voodoo economics, laffer curve. This all came out of his administration and set the path forward. There has been little deviation since from the republicans. If anything just doubling down on the worst aspects.
Again, you are turning Reagan into a scarecrow. You are taking away responsibility from all the legislation, all the economists surrounding, all the people who voted… you are assuming the democrats absorbed all of his agenda and applied it to their platform especially when they has a super majority.
You are also assuming that we were just as partisan 40 years ago when that is not the case. We did not have hyper partisan politics until ~9/11 with Bush.
Honestly I think your taking it to literally. No one who says it all started with reagan or you can thank reagan is saying the world is a perfect utopia where only reagan is the problem. He is just the face of his administration and his administration is one of the more prominent drivers of what ails us today. But yes it took other bastards. sure. All of your arguments could be said about hitler. I mean there was a whole lot of members of the nazis party besides him, but all the same hitler is the face and the driver.
I would argue that people genuinely do try to demonize regan and make him own all the issues… similarly to how in the future people are probably going to blame trump for any stupid issue we have. Much like how the right blames obama for shit.
Also, that’s a bad comparison. Hitler administration WAS a dictatorship. And anything he said was law. There is a stark difference between how the Reagan administration and all the subsequent administrations did and what hitler did.
