There's a lot more to sexism (and other bigotry) than simple economics.
Presumably, we have all had coworkers who weren't great workers, weren't very bright, etc., but managed to get ahead by schmoozing and playing politics. Their brighter and harder-working colleagues who didn't play that game didn't progress up the ladder as quickly. Bigotry presents a similar issue, but on an even larger scale.
