I see your point but you can't blame this entirely on women. Men themselves rank each other based on status / earnings. They may not do it to each other's faces but definitely there's a mental book-keeping on whose "doing well" , and accordingly many men will show more respect to people with high status. Now of course not everyone's like that, and indeed this changes from culture to culture on how pronounced it is. Also, the more capitalistic a society is and the weaker the social safety net, one can't really blame women for chasing savings and things. They and there offsprings can potentially end up in the street if circumstances go bad, so they need a partner that can take care of their material wellbeing.
