But that pushback can look different. Personally, I think that needs to be a massive general strike across every major city.
Yes, this tends to be really effective, especially when you're fighting the upper-class, which is more or less what's happening here as far as I can tell.
Get all the cleaners, cooks, hotel workers and other "servants" to strike, pool up to fund a salary-light for them while they strike, and you'll see changes quickly as the upper-class can no longer enjoy their status.
You're not fighting the upper class. It's the blue collar workers and the people who hire them who support ICE and strict immigration.
You are fighting the upper-class, while some of the working-class people are mislead to fight on the other side. Slowly but surely they'll realize where to go, but often the promises of wealth and what not gets to strong for the individuals to at least try to move up.
Who is the "We" in your statement? Are you talking about insurrection?
You mean to try to get them all and find out they're not really against what's happening? There's a reason why socialists, originally fighters for workers' dictatorship, have almost entirely switched to supporting minorities and not workers.
