There are 2 points in regards to money. The first is determining who a school accepts based on monetary considerations. I dont think you will find a gadol who believes thats ok.
The second point is the communal obligation to make sure everyone has a school.I don’t know who should pay for it and I do not envy the schools and the financial decisions they have to make. Many of these institutions are unfortunately poorly run from a financial standpoint but fixing that would not fix all the issues. I do believe that it is imperative that people should be aware of the extent of the crisis and that askanim should focus on coming up with solutions. I can guarantee you that Rav Shraga Feivel ztl and Rav Aharon ztl would be horrified with the current state of affairs.
