In the US, there are 97 men for each 100 women. ([ame=http://en.wikipedia.org/wiki/List_of_countries_by_sex_ratio]see?[/ame]). What's good for women is good for America, unless men lose out by a greater amount than women gain. I don't think that's happened.Good for women but bad for America?
EDIT: Also, a lot of what you lay at the feet of feminism is unlikely to be caused by it. Divorce rate in the US is much higher than in many of the more 'liberal' EU countries, where I'd say feminism is probably just as well founded/supported, if not more so.
EDIT2: What \/they\/ said, only they said it betterer than me.
