Are profitable corporations making 'big money' with vouchers?

The web site Oklahoma Education Journal recently posted a video ("Profitship! Cashing In On Public Schools") which warned that public education must not "let corporations take over with charter schools and vouchers."

This argument is not new in the #OklaEd community. Public education activist Angela Clark Little once said of voucher programs: "What they are about is making money ... lots of it. Big money ... and legislators collaborating with big business."

But is that true? According to the Oklahoma State Department of Education, there are 51 schools participating in Oklahoma's voucher program. They are:

1. All Saints Catholic School
