If I were a woman thinking about my career/welfare, I would start having children at maybe 18, and then be a stay-at-home mom while studying part time. I'd rush to have more than three children. I'd have my grand-parents move in with me so that they can help with the house chores, giving me more time to study. Then I'd start my career at 23-24 and have more children on the side while in my thirties. At that age the older children should be able to take care of the younger ones while I work 8-12 hours a day. Who says you have to be a cat lady if you want to work?

I think the value of children is highly underrated by women. If you have 10-12 children, you can survive a war. You can live through economic collapse and still be fine. You won't ever have to fear for your welfare, because there will always be people around you willing to take care of you. And when you get old, you can spend the rest of your days with family.
