This is amazing. If this experiment works, expect to see Louisiana’s population grown exponentially.
Even without vouchers something like 30% of New Orleans schoolkids went to private school (this was pre-Katrina — not sure what it is now).
According to family members in Louisiana, this has it ultimate roots in Hurricane Katrina. When Katrina devastated New Orleans, it damaged/shut down many, many public schools. And the political bureaucracy was moving at a snail's pace to get them re-opened. Unsurprisingly, the Catholics had gotten their schools back up and running in a few weeks.
So many students were being left uneducated that the Catholic church opened the doors of Catholic schools to many of the public school students "until the public schools re-opened" as an act of charity. This worked out so well for the kids that the kids didn't want to go back to the public schools.
This example convinced many formerly "anti-voucher" pols that vouchers might not be so bad after all.
