You seem to be advocating that no one American even talks about taxing the wealthy so that there isn't a "pressure relief valve"?!
In the world of shit that is American politics right now, your solution, out of all the things that possibly change, is to silence anyone suggesting that just maybe there's a better way?
THIS?! This is what you would change? Remove even the discussion of anything even slightly left of the Clintons?!
Are you insane? Are you Nancy Pelosi? Are you JD Vance?
Do you hate the Democratic party so much that you want to remove all traces of progressive politics from it?
I've got news for you. The water is boiling and the lobster isn't climbing out. Putting the lid on and turning up the heat isn't going to work. Throwing younger lobsters in the pot isn't going to work. And silencing the only people talking about turning the heat down isn't going to fucking help.
I don't want to take away from your other excellent points about the American economy, but I think you missed the point about public.
Public like schools. Public like free education for anyone bright enough to pass the entrance exams. Public like investing in the future talent of the nation. Public like genuinely free tuition.
It's cheaper than forgiving private loans because the banks don't earn any interest in the first place.
It won't happen in the USA of course, but that doesn't make it a bad idea.
