I disagree with your POV. Don't idealize the non-Western working class, because people outside isn't progressive, revolutionary or extremely class councious. What makes them revolutionary is their material conditions and the work of some existing organizations which are disputing their conscience. For example, the Brazilian mainstream media is more pro-Israel than the US media. If you ask Brazilian people about Muslims, most will associate them with terrorists, and even so we have seen some growing support for pro-Palestinian movements.

So I completely disagree, you need the same effort of propaganda and agitation work even at the core the empire. The working class is very fragmented, we have very specialized professionals in tech with entrepreneurial views, the office worker who becomes a drag queen at night, the bigoted factory worker, the gig worker that does not have a stable job, and many different others. They all can be revolutionary, conservative or reactionary. Organizing a very heterogeneous class is challenging, but there's no other way. And while promising revolution is good, most people have immediate needs that need to be addressed. In order to effectively organize you need to keep an eye on the now and on the future, and try the best you can to make both those views converge.

And keep this in mind, if the existing political work is not producing fruits is not because your workers are inherently bad, but because our existing analysis, strategy or tactics are wrong.
