What I am after is a Marxist perspective on companies and specifically joint-stock companies which I wasn't sure how much older texts would have touched on. But since then I did find out that Marx has written quite a bit on stock companies (even when they were still premature at the time) and how they disrupted the old social relations deriving from simple, private ownership.

Anways, thank you for your advice. I must read Imperialism at some point.
