What were the political differences between the US and the USSR?

Primarily, the major differences in the system of government, but also the general mentality of the common people; rugged individualism being rappent in the US - each person representing the bourgeosie - the every man was more focused on the pursuit of his own rise of power. By contrast, in the USSR (in the former part of it's regime at least) people were generally more focussed on the interests of the state rather than the fufilment of one's own goals.

This led to a vastly different social structure and class system between the "East" and the "West".
