Speaking for the general strike, there are arguably a number of reasons why that’s a lot harder to get rolling in the states. Social safety nets are laughable, worker protections are shittier and union busting is greater than a lot of other nations. A lot of people keep their heads down and don’t act up for fear of loosing what they have.
IMHO complacency oversimplifies and ignores the root causes behind collective action or inaction.
And that said, when it came to shit like ICE, and communities literally have nothing left to lose, that shit gets fucking LOUD in a city. Block by block citizen patrols, lots of organization, etc. But that doesn’t seem to get a lot of press in the news, and people assume Americans are just taking it lying down.
