I don’t think you realize how much torah the AMERICAN government is supporting. There is food stamps and free daycare available for low-income students, even if they are full time yeshiva students. There is also HUD/section 8, WIC, LIHEAP, medicaid, and various other programs. There is also Fafsa and many other forms of aid that yeshivas in america get from the government.
If the American government would decide to suddenly not give any of these benefits to people who are learning in yeshiva or kollel, I would certainly think that is wicked discrimination. Since these programs are being funded by taxpayers, all citizens should equally have the rights to receive these benefits.
So the same way public schools and colleges in israel get this funding, why shouldn’t yeshivas? Ah, because what the yeshivas are doing isn’t as valuable as studying Japanese folk songs in a liberal arts course? If so that is absolutely rishus, no doubt about it. A “jewish state” should know better.
