I’m going to categorically refuse to pay more than the school’s annual budget divided by the number of kids.
See DY above: “Also, having spoken to several administrators, I believe that it really does cost the tuition fee to educate your child, and the parents who can’t afford full or close to full tuition are being subsidized by the donations given to the yeshivos.”
It really costs full list price to educate your children. The poor children’s subsidy is coming from donors not other parents.
