@finner Just as to amass wealth in a Leninist society you don't need to be a Lenenist. You don't need to be a capitalist in a capitalist society to amass wealth. You can work to be 'successful' (or at least wealthy) within a system without actually caring much for that system.
Often the best way to get wealthy is actually to subvert the system, use game theory to exploit the weaknesses of the system. Both in capitalist, socialist and communist societies do people do this.
@Schouten_B I'm not sure we're going to get much further in this discussion. We seem to have some differing interpretations and definitions we're going by. I'm not an economist and probably not incredibly well read I suppose, but as far as the things I have read and the way my understanding of the definitions of these things, they don't seem to be jiving with yours.
