Earlier this year, Nathan Robinson of Current Affairs wrote an article against school vouchers. He argued that private schools would be so focused on profit that they would sacrifice quality, and that competition wouldn't be enough to keep them in line.

I counterargued that yes it would, and cited among other things the success of food stamps (ie "food vouchers"). These give poor people access to the same dazzling variety of food choices as everyone else, usually at reasonable prices and low profit margins. If school vouchers worked as well as food vouchers, they would succeed in their mission of improving choice without sacrificing quality.

Now Robinson doubles down, sticking to his anti-voucher position and also proposing A Public Option For Food.
