Without children, men have more liberty to earn less - that is, they are free to pursue more fulfilling and less lucrative careers, like writing or art or teaching social studies.
Women and men look at their life, and women say, 'What do I need? Do I need more money, or do I need more time?' And women are intelligent enough to say, 'I need more time.' And so, women lead balanced lives; men should be learning from women.
So we've moved from an era when women's biology was women's destiny to today, which is an era in which men's biology is men's destiny.
I've gone from being quite wealthy, when I was defending women, to being quite poor defending men.
