Yes, I know why they get paid more. The point I was trying to make goes along the line of "if there's an audience for it and it generates more revenue for the sport/entertainment industry, then you get paid more. No one wants to watch women's sports and so they don't generate the amount of revenue men's sports do, so they don't get paid more. The same with the p0rn industry. The vast majority of revenue comes from straight men, so naturally the women are going to be paid more.
There was a good point made from a sports media guy and he stated that women's pro basketball, women get paid 20% of the total revenue brought in, while men in their league (NBA) get paid only 7% of the total revenue brought into their league. So even in sports men are being paid less than women, if you go with what they're bringing in.
