College is pretty different than grade school. It's a lot easier for adults to understand whether or not they're learning well and to see where people end up following graduation. You'd have a hard time convincing me that the way an 8 year old is taught today will lead to better results in better outcomes decades later (after those that ran the schools have retired and have thus left the market). Further, how many Harvard-level grade schools do you think we can run as a society? Given that private school pay is substantially worse than public school pay on average, how could one say that private schools, again on average, would outperform public schools?
