How so? Do you have any particular communists in mind? Which communist nations have you spent time in?
Communism doesn't have capitalist institutions, therefore this sort of behavior is non-existent in a communist country.
I'm curious which specific communist behaviors inform your comment here.
The USSR. Cuba. Communism is crap, and the countries stuck with it end up sucking for obvious reasons.
EDIT: Oh wait, just noticed your "location". Eewww.... goodbye. Sorry, the USSR fell a while ago. Good riddance.
