Why is it that girls are intelligent than boys at school but boys end up being successful and rich when they are older? (Patriarchy strike)

Boys often do well in schools as they grow older - girls tend to be more mature than boys at a younger age, but boys catch up. Of course, that doesn't explain why boys tend to be more successful in the long run! Unfortunately, much of the world is still stacked against girls - boys often get paid more than girls for the same job, and get promoted more quickly just for being male. Men are pressured by society to succeed in the workplace, while women are pressured to get married or have children. While many women will fight the double standards, many women will get disillusioned and give in. Women bear the blunt of childbirth and childcare as well - they end up sacrificing more of their career for the sake of their family and children.
