I felt like a bad Leftist not knowing Lenin's imperialism theory. Now I can cross this off. Main points are: - capitalism is in its latest stage, characterized by monopolies and the dominance of finance capital - capital gets exported to colonized countries - the working class in the imperialist countries benefits from the exploitation of the colonized countries - Kautsky is wrong and we don't like him - monopoly capitalism intensifies the contradictions of capitalism - capitalism is decaying

I find it interesting that we've been supposedly living in "late stage capitalism" for over a century now. Maybe it's time to stop being this optimistic.
