anon for this- This is what caused my school to close down when I was in early elementary school and had to homeschool (or go to public school C”V). There were about 40 families sending their children to the cheder and only about 3 (including my family) paid full tuition. Some paid half but the majority were children of teachers in the school and could not afford to pay much at all. And of those 3 who paid full, they were the ones who had few children in elementary school. (we had no frum high school at that time. Who knows what we would have done if the school lasted that long.)
There must be a solution! I wonder what happened to those neshamos that went to public school… I heard that some are not frum anymore…
