this is true, but you can look for additional options. Wife can stay at home while kids are small, if she likes it; no need for “universal pre-k”, kids can chant alef-beis at home and with friends.

There are cheaper schools with inferior general education that you can supplement at home with online classes or full-fledged schools. Time you have with your kids is worth the effort.
