It seems to me that one of the fundamental and historic issues is the disinclination of most , if not all yeshivas, ( be they MO,Litvish or Chassidish ) of opening their books to outside scrutiny. Some the yeshivas in the 5 Towns on LI floated the idea of getting access to school tax funds until it was pointed out that with the money would come the same requirements that the public system has: an open budget subject to
voter approval and an elected board ( the voters in both cases would be all registered voters, not just parents ). They thought they would get the money with no restrictions.
I understand the plight of BY. But I don’t think they can ecpect outsiders, with their own schools to support, to just throw money without some assurance of how the money is being spent, what the budgeting process is, and how they determine their scholarship needs.
