Sure we all need to make a living and a school tons of employees to pay not just teachers but secretaries and janitors etc… BUT a frum Torah school is still based on raising children in chinuch-not on money-and that’s what should be making the decisions in the CEO of a school if something should or should not be done. Of course every school has their own daas Torah Rabbonim to turn to when it comes to serious halachic questions regarding if the school should or shouldn’t do something.
But in a Torah school the difference between accepting or not accepting a child into YOUR OWNED SCHOOL should NEVER be based on if the person has or doesnt have money.
