Of course, but unless you think women are innately superior, wouldn't they be at a disadvantage because they work fewer hours? In other words, if your system is based on output, and men and women are equal, men should be expected to perform better because they work more hours.

Of course if a woman produces more output or is better, she should be paid more. My point is about how you should expect the average result to be in men's favor though, unless you think women are innately superior. If you work 8 hours a day and I work 9, I'll probably be ahead of you at the end of the year, unless you're a lot better.
