This is a common misconception that homeschooled kids are not socially adept. Having met many homeschooled kids I can confidently say they are very social and good conversationalists in general. Of course it depends on the parents but kids naturally seek out the social balance that is right for them within the community they live in.

The other point I think that is important is what isn't taught at school. Life skills. Cooking, financial knowledge, entrepreneurial skills, first principle thinking, value of directly volunteering, household management, work life balance, stress management etc.

All these are seen as less important than learning the entire list of presidents/kings of a given country, or deriving equations that you will never do again past that exam. I think its questionable. Maybe OK for some kids. Maybe not for others. The only way personalised teaching can happen right now is via homeschooling as I see.
