"so its unfortunate that females happen to have the most amazing gift of all, children ?"
It's not gift that women can have children - some kind of magic. It's biology. Whether they have to have them or not is a choice. The old argument that the species will die out is simply garbage considering the world pop grows every year.
so no it's not unfortunate. It's they way it is. Choose to either breed, or not to breed.
"And whether they are worked into the ground or not is ultimately a gender question?"
no. it's a choice. My wife and I have No kids through choice and she certainly isn't worked into the ground. We both work in the same industry, make good bucks (similar wages for similar work).
