That's not how genetics of sexual reproduction works. I think it's only fair to say that we can't truly do a qualitative measure of the impact of any condition on fitness.
1) Being a hinderance does not necessarily mean evolutionary dead-ends, and some traits can still be prevalent in populations because the diversity is what protects us from systemic environment shocks.
2) Perception and adherence of hierarchies and status symbols are things present in nature for millions of years. "Capitalist society" has nothing to do with it.
