A more rational description of this behavior is selfishness or insatiability. In reality everyone acts in their own interests - some people just choose to deny the fact, and attempt to disguise it.

Ranting about greed and racism are popular past times of the left. Usually they refuse to see the logic in the reality that greed is a more powerful motivator than racism, sexism, or most other -isms. Given a choice between being racist, being sexist or making money, the capitalists they complain about will choose the money nearly every time. Racists and sexists in a 'greedy' capitalist society make themselves poor.
