The IQ of children is highly correlated with the IQ of parents. Adoption is not, for educated couples, an alternative to having their own children.

You can make things as equal as possible, but no more. My wife and I have almost identical educational backgrounds. We accepted very similar jobs out of school (she will technically be making more money than me considering benefits). We had our baby her last year of school so she wouldn't have to take maternity leave, with the negative stigma associated with that. I'm taking a couple of years off from working at a large law firm so I can work a 9-5 with a judge and take more baby responsibilities and allow her to focus on her career. We're trying extremely hard to make things as equitable as possible between the two of us.
But at the end of the day if my wife had suffered a complication in child birth (it is still the most dangerous thing most people do), it would have fallen to me to provide for her and the child. I was not the one who had to take that bodily risk, therefore I assumed by default the "provider" role, or at least had to be fully prepared to assume that role. Therefore, it was totally rational for her to have been concerned, pre-marriage, about my ability to do so.
That's some useful education.
This is the most depressing thing I read in this whole thread. The idea that one should view raising "highly successful" children as some kind of outcome they can control or influence through "high IQ tigerness" and cold economic analysis is humorous and sad all at once. Coupled with encouragement to not buck a pointless social tradition because it may make (shallow, deplorable) people judge you as less worthy and thus may negatively impact your future prospects of becoming more like them seems like a rather sad way to live life, but I guess we all have our own goals. The fact that after thousands of years our species is still mesmerized by shiny rocks we dug out of the ground is also odd to me, but apparently not others.
Like BBC radio 4 has a leftie, public-services-union-member audience and a rightwing traditionalist audience who are largely unaware of each other, HN has an ivy league educated randian-hero readership and a more old-school, "just give me an ounce of weed and a hex editor and I'm happy forever" readership, and both is convinced the other is intruding on their community.
There is plenty of research to suggest that socio-economic (SES) status is the driving factor behind IQ, not genetics. An adopted child's IQ will tend to be higher if adopting parents have high SES
Adoption.

There are some limits to what can be shared. I advocate going right up to that line. A woman who wants to raise a baby at some point has to make tough choices about formula, breast pumping, bonding, and her other priorities in life. There is a qualitative difference between the handful of hard limits imposed by biology, and the many limits imposed by compulsory monolithic gender roles.
