Texas has private schools and people are free to choose them.
Having government fund them is the question, especially if the government gets to regulate them.
I don’t know about private school vouchers. For example, a students sits in a private school, his parents are working hard to get the $500 dollars a month to pay for it, and all of a sudden a student waltzes in, $500 dollars a month paid by the taxpayer. How, exactly, does that make sense?
