I have pretty mixed opinions on whether it's a good thing, was mostly home schooled myself (some private and public school too) and ended up in foster care voluntarily for some years. Home schooling vastly increases parent control over their kids, considering how "I can teach my kids better than schools can" selects for traits like narcissism, it can get messy. Peer social interaction is definitely an easy thing to mess up as well.

Heard some true horror stories in foster care, like a guy who grew up "homeschooled" by meth addict parents who faked tests, forced him to steal to get back in the house (at least at some points), and left him almost illiterate at 18.
