Should Women Make Equal Incomes?

I used to think so.  After a little consideration, however, I notice that men have god knows how many social obligations to do everything for women.  If taken out to eat, it is customary for the MAN to pick up the tab.  When dating, the MAN is supposed to buy her expensive shit, like jewelry, to name one. 

As long as society pressurizes and expects men to wait on them hand and foot, I think the fact that men tend to make higher incomes is justified. 

I can point out some fun facts from Sweden:
1. Girls have on average better grades in every single subjec except sports.
2. Out of all people that graduated from a university last year, only 35% were men.
3. More women than men have graduated from a university since 1977.
4.Yet the swedish average woman get 20-25% less income than the average man.
Best person for the job, yeah right.
