A civil war, mass riots, general strike, etc. only happens when people are really suffering. For the most part Americans are still doing pretty okay.

American society is also atomized. Mass political movements are rare and often fizzle out like occupy wallstreet or BLM. There’s widespread dissatisfaction with politics in general. So far nobody has found a way or even wanted to tap that besides MAGA

You’re overlooking that MAGA is an actually revolutionary movement in many ways. The revolution is already happening with Trump at the helm. It’s not going the way you want.
