Kids don’t have 20 years to wait for some voucher bill to pass, and then new schools to open up and then bad ones close down and better ones open up, all while social infrastructure develops to circulate good information about outcomes so parents can make informed choices, and backstop laws and bills to prevent islands of no-schooling or no-good-schooling to be passed either.

Both solutions take time. One solution injects a whole lot of the worst capitalist incentives into education (grift, hype, profiteering), the other doesn’t.
