I actually am one of those parents. Childcare and education are actually two different things. They tend to be combined into one in schools, but that isn't the only approach.

There is also college education, which is a bit different. I could see many people choosing to simply pay for an institution to give them tests to prove they actually learned the material, while the actual learning is done independently. If you against this, well, you sound like someone who had their college paid for by their parents.
