I think I ended up pretty well being homeschooled. Unfortunately not everyone can be trusted to do a good job of educating their own children. I think it would be great if they could. Also I don't think the current school system is anywhere near a good idea at all.
Pretty much exactly my viewpoint. I was homeschooled from kindergarten through seventh grade, and while my social skills have taken a while to recover (helped that our house was thirty miles away from like anything), I'm pretty well-adjusted and rather smart. But I know people who had much worse experiences. When the kids never have to leave the house and they're not old enough to call child services themselves (assuming they even have phones and can get to them and use them without their parents finding out), some pretty bad [dukar] can go down. I'm a libertarian, but I'm also a human, and I recognize you do need some government intervention sometimes.
But you know, I don't think a fully privatized school system would necessarily be all that bad. We have a privatized food system, so to speak, and that seems to work out alright. It's extensively inspected and regulated by the government to make sure it's safe and good and all, and there's food stamps if you can't afford it. The government can assure the quality of our food while leaving the production of the food in the hands of much more competent, less wasteful people, and giving us the freedom to choose the foods we want. Seems to me like you could do the same thing with schools.
