Many people can't afford to pay twice for school tuition. Once via taxes, and then again to pay for private school tuition or home-schooling. Government run schools have the monopoly so most children are forced to go to schools closest to their homes. I agree with some that a system should be in place to allow parents to decide, not the federal government where and how their children should be educated.
