I bet my cousin doesn't even average 2 hours a day and her kid is a teenager and has been homeschooled his whole life. I never quiz him on book stuff, but he's a very smart kid in the important ways like problem solving and common sense, well ahead of his age. He's also very independent in ways I don't see from other family that age. The school-goers seem to all be instruction followers now. I know if I ever have kids, homeschooling is not negotiable even if it means me quitting a good job to work at night in a sucky one and making myself get by. Not just for the anti-indoctrination, it just seems to make way more rounded people to me.
