It looks even less feasible than it does in countries with a far greater social conscience than the USA ever had. Come on, get real. Even a hundred years ago in Europe, with mass unionization, with the de-facto religion of communism running riot, with millions of angry factory workers empowered by their role in a recent world war - even then, general strikes never came to anything. What are you guys reading - or smoking?
The only way to change things for the better - I mean to really change them, not to turn society upside down and end up worse off than when you started (c.f.: communism) - is slowly, incrementally, patiently, by persuading people, by getting involved in politics locally, by being the change you want to see. The rest is pipedreams and delusion. It's too boring and "milquetoast" and "sell-out" and "bootlicking" (etc etc) for you guys but unfortunately history is very clear about this.
