My opinion is that students not on classrooms are much less prepared to deal with those, according to you, non "well-socialized" students from traditional schools.
Children who grow up spending the majority of their time in school are raised by their peers, rather than by productive adults. They look to each other for behavioral and moral cues. I have found that students from classrooms are, on the whole, rude, lazy, arrogant, cruel, apathetic, jealous, dishonest, narcissistic, anxious, and depressed.
I admit that their ability to not embarrass themselves among their peers is greater than those who are homeschooled or from experimental private schools, and their traditionally-schooled biting, ironic sarcasm is unmatched among the more naive non-schooled population. Traditional schoolchildren are also much better at taking instructions, falling in line, acquiescing to the wishes of their superiors, and bearing assaults on decency and freedom without complaint.
I made it through 12 years of public school and am extraordinarily "well-socialized", and I am disgusted by what it took to make me that way. It's only now that I've been out of school for about a decade that I've finally started to turn into a human being.
