At the end of the day has very little to do with MAGA(TM) or Liberals(TM). They're just the current characters in a script that's been played a bunch of times. Kinda like how you can set the basic plot of Romeo and Juliet in any century. From the Tea Party to the Ron Paul thing to the Bernie bros to MAGA the populist movements will keep arising so long as the "we know what's best we're so smart" crowd continues to do things at the expense of the average person. Whether that's back handed environmentalism or facilitating monopolistic big business (or both, for these two examples often go hand in hand) doesn't really matter. The average person doesn't like it even if they can't quite articulate why. And so the populists will keep coming, until one day one shows up that the system can't de-fang. Who knows what'll happen then but I'd bet a lot of money we won't get a stronger EPA or a more favorable environment for big business out of it.
