In some of your other posts, you've said that you support universal public education, but that seems to directly contradict the statement you've made here.
Government schools have no competition, at least where I live. When I was a child, my parents paid taxes, which paid for government schools. They had no choice but to send me to terrible schools because they couldn't afford anything else after paying their taxes (my parents were not rich).
Attempts to compete against government schools are always rebuffed by people as being "against public education". So which is it? Competition is always good or government schools are somehow sacrosanct, or neither?
