The sort of “socialization” that home schooled kids get is far superior to that in public schools. In PS the kids have role models who are older children. At home role models tend to be adults. The whole purpose of education is to teach and prepare children to be adults, not to grow up to be children in adult bodies and in their parents’ spare bedroom. I am old enough that I have seen the progressive infantilization of adults. We all know too many 30-43 year old people who have not attained adulthood and there are more every generation.
Thankfully most overcome the dysfunctional socialization learned in school and go on to learn the healthy social skills needed to live reasonably successful business, home, and community lives. Sadly some don't.
