The risks of universal vouchers are quickly coming to light. An initiative that was promoted for years as a civil ­rights cause — helping poor kids in troubled schools — is threatening to become a nationwide money grab. Many private schools are raising tuition rates to take advantage of the new funding, and new schools are being founded to capitalize on it. With private schools urging all their students’ families to apply, the money is flowing mostly to parents who are already able to afford tuition and to kids who are already enrolled in private schools. When vouchers do draw students away from public districts, they threaten to exacerbate declining enrollment, forcing underpopulated schools to close. More immediately, the cost of the programs is soaring, putting pressure on public school finances even as private schools prosper. In Arizona, voucher expenditures are hundreds of millions of dollars more than predicted, leaving an enormous shortfall in the state budget. States that provide funds to families for homeschooling or education-related expenses are contending with reports that the money is being used to cover such unusual purchases as kayaks, video game consoles and horseback-­riding lessons.

The voucher movement has been aided by a handful of billionaire advocates; it was also enabled, during the pandemic, by the backlash to extended school closures. (Private schools often reopened considerably faster than public schools.) Yet much of the public, even in conservative states, remains ambivalent about vouchers: Voters in Nebraska and Kentucky just rejected them in ballot referendums.
