Not to sound like a sexist asshole, since I don't necessarily support the gender pay gap, but If I could have been born a man or a woman I'm glad I was born the one who gets payed more. Closing the gap, while the right thing to do, is still a threat to that gender advantage. I can understand why not everyone would be reluctant to change.
As far as being a politician goes, it requires a certain degree of manipulation, charisma, leadership and composure that not everyone has. I like to think, theres a reason those people are doing it and not me. So I don't question their motives and mock them as much as many people.
