Why are WNBA salaries lower than NBA salaries?

The salaries in the WNBA are lower because the league has no fan support,no ticket sales revenue,no advertising dollars,and no tv contract worth crap. In essence the league loses money because of lack of interest. In the real business world the league would fold. The NBA subsidizes the WNBA so losses are offset. David Stern is showing his business acumen by keeping the nonsense afloat. The pay discrepancy has nothing to due with sexism, it is merely economics. The realityy is that they are overpaid for the profit that is generated.
