More than 15,000 low-income students attend private schools in South Carolina. Their parents scrimp and save. They make sacrifices. They’ve put their children’s education at the top of the family’s financial priority list.

Those parents also pay taxes. More than $8.5 million this year in state income taxes alone.

Much larger than their contribution to the government coffers is the sum they save other taxpayers. If those 15,000 students enrolled in public schools and were funded at the rate of the existing public school students, it would cost state taxpayers more than $72 million. Taxpayers below the $35,000 income class would not pick up that slack; it would be borne by those with deeper pockets.
