Tax dollars and private schooling

So I currently go to a private Christian school. This is one of my text books. These text books are a MUST to graduate through the program that most Christian schools go through. On that note, Betty DeVos (Head of Education for the US) is currently trying to get "vouchers" for private schools. Another words pouring federal money into private schools that can teach ANYTHING they want to and force ANY dress code they want to without the government saying anything about it. I don't know about y'all, but I don't think this is right.

(Update) This is how the woman in question, the one that entangles men and leads them to death, is portrayed as. The school I go to doesn't believe in anything for women. No make up, pants, nail polish, jewelry, dyed hair, or skirts/splits in skirts that go above the knee.
