Feminism teaches women that they should go to college, establish a career, and then (if desired) have babies. The degree part is termed by Dalrock as a feminist merit badge. This is considered to be the bare minimum that a feminist woman should attain. Then comes the establishing a career part. For whatever reason, this seems to normally take a woman until the age 30 to do. Could one establish themselves in less time? Perhaps so, but there are incentives not to do so. And then it is time to make babies.
Does this script make sense? Well, it depends on your perspective. If you are a woman who desires to maximize her youth and beauty for fun, validation, and lastly career advancement; then the answer is yes. If you are one of her perspective children, the answer is no; as babies are best conceived when the mother is young.
If your are society, the answer is no also. For all of that training and experience wanes for the woman during the time she is a SAHM. Can she effective restart her career? Maybe yes, and maybe no. So as a result perhaps she loses, her family loses, and society loses due to her decision to pursue career first.
Would it make sense to flip the order of the activities? That is, babies first and career second. Go to college when forty; get a fresh degree and go do what you want to do. This does seem to have an effective ring to it. Perhaps it should be attempted more.
The obvious question is, “Why is the career-then baby script sold so hard”? Probably the biggest driver is for woman to take advantage of their youth and beauty for fun and profit. Which seems kind of selfish.
