While siphoning the remaining public school funding to private schools [1]:

> ProPublica analyzed data from 13 states of varying sizes that do publish private school directories and offer public funding to these types of schools, and found that at least 1,500 more are listed today than were five years ago — bringing the total to more than 9,600. The numbers provide a rare look into the growth catalyzed by friendly legislatures and government money, while public school districts are losing students and closing schools.

> When public money is available, most private schools take advantage of that funding. In several states, all or nearly all students at some private schools pay tuition with public dollars.
