Joseph, there is a limit to how much tzedaka I can give. And I still think feeding kids food takes priority over teaching them science. So that is where I make my priority to give.
Mazal, I am sorry that you had a difficult time. However, if a large enough portion of the student body isn’t paying enough, and funds aren’t coming in, what is a school supposed to do?
As for homeschooling – I think its a lot more practical than people think. Coops (where parents help each other out with subjects of their strengths) are also very feasible. You can’t teach math – that’s ok, another parent isn’t great at teaching chumash. Younger grades are also easier to homeschool because most people know the basics.
I guess BYoBP has to decide – educate those that they can afford to educate, or force 2100 students to lose out.
