With dramatically higher demand for women programmers, would it be permissible to pay women far more than men? How would this affect gender relations in the workplace?

Assuming that currently 20% of programmers are women, would 60% of the current programmer population (or 75% of current male programmers) have to go unemployed until more women had entered the workforce? Following from my first question: if we think paying men and women differently is a-okay, what would this 25/75 split do to the salary of male programmers? How would this affect gender relations in the workplace?

Would these same quotas apply to universities as well? How would the market react to universities making cuts in graduation rates to accommodate occasional fluctuations in the woman student population?

What kind of grace periods and permitted lag would be allowed? If I fired a woman, would I have to fire a man to make up for it that same day? That same week? That same month? Would I just have to refill that position with another woman? What if I decided to eliminate that role entirely?

I am not convinced that you have put thought into your proposal. It makes for a good sound bite and I don't doubt that your intentions are noble, but it is not a good idea.
