Not arguing the point - however the voucher programs that I have read about generally give state money to the student, not the school, so the student and family can choose a school. If this money ends up in the hands of a private Christian school with no strings attached, that's a good thing, right? Agree that strings will lead to corruption, but does it have to be that way?
Do you know of a single program that DOESN”T have strings attached?
If a school takes the voucher State money (and it will come from the State), in a few years the majority if that school’s income will come from voucher students. Then someone will say “You know, Christian School XYZ is _________. I say we cut funding for them until they teach _________”.
The school will then have to decide if they give up the funding, or stay true to their beliefs. After many battles over the years, I know the answer will just about always be to keep taking the money.
This is why there are very few Christian hospitals left, and almost no adoption agencies. They started taking State money, and ended up organs of the State.
