Joseph, please address homeschooling. That would alleviate MOST of the problem because kids at BYOBP are from predominantly from frum homes. Wouldn’t that remove the pekuach nefesh? Also, parents could for coops – basically small groups with each parent teaching a few kids. No need to exchange money. Obviously that would only work if one parent was home.
Yes, older kids should be working to pay tuition if their parents cannot. Scholarships (especially in hard times) should be given as a last ditch effort, not as a first resort.
I have no problem with professional courtesy, provided it doesn’t harm the paying customers. Phone companies give thier employees cheap phones, tuition is not really different. Unless there are too many employees vs customers. It needs to balance.
