I think it's real ... or has potential to be real
there are Americans who keep this place alive

Years ago, Set and I went to a pottery museum with a former colleague of mine and her family. They're extremely born-again. The parents were more than a little peeved with the exhibits that had dates like 4200 b.c. noted on them. There was a lot of family discussion in the corners of the museum. The kids seemed positively amazed by the date notation.
The thing with the private religious schools is that parents can use government-funded education vouchers to pay for their kids to attend. So, one way or another, this sort of thing can be government-funded.
Amazing to the non-Americans in the audience eh
