I don't think we are to the point where a general strike would be something almost anybody would go for. It's going to take something more visually horrific to move people to take that up and risk it all in any way. That said, from a purely math is math standpoint. The run-up below and those numbers brought the economy to its knees for a time. I talk to a lot of people who still think that something like 25-50% of Americans were behind on their mortgage payments during the Great Recession, without realizing that, generally, the number wasn't anywhere close to that. Numbers are big and scary, and it doesn't take much percentage-wise to get things moving in the wrong direction and right quick.
If 10-20% of folks start sitting things out (and yes get laid off and consequently no longer spend, pay taxes to service our enormous debt etc, etc etc), it would get ugly in a hurry.
Or here is another one. That shows it doesn't take much. 14.8% was peak unemployment during Covid and for a lot of businesses, investors and the government that was some shaky ass uncertain times for a bit.
