I like the nightlife, and I’ve got to boogie, so I’m pleased to hear of a new organization called DISCO: Democrats Impatient for School Choice Organization.

There are many ways to shake, shake, shake that education policy booty, however, and if DISCO really wants to be family friendly, they would be better off skipping the voucher element of their choreography.

The organization’s goal is to extend real school choice to low income families. A crucial element in achieving that goal is to ensure that parents, not influential lobby groups or entrenched interests, get to decide the kinds of education they can choose.  Based on both my review of the historical evidence and my recent regression study of modern school choice programs, vouchers are prone to regulatory proliferation. They centralize authority over what a voucher can buy, so that parents who need financial assistance cannot escape whatever limits the politically powerful wish to impose on them.

Tax credits are different. Scholarship donation tax credit programs, such as the one that already exists in Pennsylvania (and which the state House has voted 190 to 7 to expand) create a proliferation of different sources of financial assistance for low-income families. So if one of those sources decides to impose a particular set of rules on how the money is used, it doesn’t affect any of the others. Parents can choose to seek financial assistance from whichever scholarship granting organization most closely matches their own values and preferences, thereby preventing them from being forced into a particular set of choices.

I made this argument in a little more detail in Cato’s amicus brief in the ACSTO v. Winn case, in which the U.S. Supreme Court recently upheld Arizona’s scholarship donation tax credit program.
