There are significant barriers in place for revolution in the US. The Proletariat is still under the belief that supporting US Imperialism will benefit themselves more than Socialism. Additionally, theory is frequently coopted by Trots and other impractical forms, resulting in people endlessly seeking to critique society, not change it (your Noam Chomskys and the like). Moreover, labor organization has been millitantly crushed.
I recommend starting with theory. I have an introductory Marxist reading list if you want a place to start.
For elaboration on Chomsky, I recommend reading On Chomsky.
