OK, I'll upgrade my commitment to 9-10 months plus breastfeeding, which brings it up to, what, 2 years max? :) And don't forget pumping and saving milk, but that's also a bit of a modern convenience.

Women may be designed to actually give birth, but that doesn't mean they have to be in charge of raising the children afterward. It is, technically, a 9-10 month commitment on the outside, and after that, men are just as qualified to raise children, if *they* can get over their gender roles phobias. Happy family, happy society, yay, we all win.

That's not true. Specifically, I know that there has been a big push to get more men involved in education. The motivation for this is that young boys (and even teenage boys) who are behaviorally disruptive in class respond very well to a male teacher. And that's a win for everyone. Unfortunately, teachers are not well-payed, so it's hard to get people into the field, period, let alone men.

Also, re:

Try taking a look at MA/MS/PhD enrollment in those fields. Much closer to 50/50. No one really cares about undergraduate degrees.
