If you're talking about the US, secession and balkanization is a significant possibility for how the US ends. It'd be much easier to make changes on a state level.

Also, look at former Yugoslavia and USSR and how the constant inflow of bullshit has people believing capitalism is good actually even though it turned their economies to shit and continues to exploit them and suppress their development to this day. But those regions are just where it's more obvious. Class consciousness is suppressed all over the Western world.

Cutting down the US's ability to manufacture that bullshit is the best thing Americans can do not just for revolution at home, but all over the world. Ironically that while liberal propaganda keeps portraying the US as 'saving the world,' by dismantling itself they actually could save the world from capitalism.
