For the record I am against the efforts to get government funding for private education. It will only cause problems. I do agree with the plaintiffs in this case. If the government is funding private education without policing any of the curriculum then why are the religious schools being excluded?
However from a frum perspective government funding of private schools would be bad news. There will almost certainly be rules attached that will exclude Yeshivas. There will also be rules that will greatly increase costs of education and in places like Lakewood and Monsey where the frum community is the majority they will be the ones bearing the bill anyway through their school tax portion of the property bills. Plus you can be certain that down the line the government will make rules that will cause major problems for Yeshivas.
To put things in perspective the Catholic preschools (who unlike Yeshivas have no issue with accepting non-Catholic children) are fighting AGAINST Biden’s Build Back Better funding of preschool education saying that there is no way they can comply with those regulations. That boils down to the (1)government funding of free preschool but (2) but only if they are aren’t religious. That would put them out of business. (Same principal as this court case)
