1. The federal government will pay for vouchers, to some extent, and thus extend its control over schooling. Admittedly this is happening anyway.
2. No politically feasible vouchers program will apply immediate depth charges to current public schools or even reduce their initial budgets (“oh, you aren’t letting public schools compete…). That means the new money must come from somewhere. That means our taxes will go up.
Vouchers would create a new middle class entitlement, ostensibly aimed at education but often simply capitalized in the form of cash. In the meantime public schools would require additional subsidies to stay open. How pretty a picture is this?
