a: make it so that ANYBODY can get a hot woman, which makes having lots of hot women about useless
b: flood the industry with women. This is happening slowly, but you can't force it. Of course, if the balance tips towards women, then we'll just have the opposite, and having hot powerful handsome men around will replace hot women.
c: (myriad of ridiculous examples about fundamentally changing our species and the nature of sexuality)
You have to remember this isn't about sexism. It may well be sexist, but all it's about is having what all of your peers want but can't have makes you look powerful. It just so happens the most common want-but-can't-have is attractive women. "making it better" can only be achieved my removing the want.
