Ah, what DY said is actually really interesting.
I had actually assumed people were always suggesting that the goverment either pay in full for Yeshiva tuition or give a tax break for the full amount. Now, I think I understand a little more.
If you live in a town in which $2000 of your yearly income goes to funding a public school that you don’t even use, why not get that money back to use on education. That’s what it’s for, right?
I know the answer to my own question though. That would open the doors to everyone without kids opting to get the money back, plus everyone going the private schools. Those left sending their kids to public school would get hit with way higher taxes. In principle, I agree with CT Lawyer, but I don’t vote on principle so that’s irrelevant. I would always support the voucher system; frum yidden shouldn’t advocate for all of us having to spend thousands more per year just to satisfy a multiple century old document written by goyim (the constitution).
