AZOI.IS:
Very Good. You have found the fallacy of the argument.
No Gadol will embarass anyone to pay tuition because:
1: Tuition is not a neccessity
2: Tuition is covered anyway by the community
3: Embarassing someone who has no skills, no education and a large family (all by choice and recomendation of these same Gedolim) will not help them pay. The gemorah is dealing with someone who would be able to pay if they were embarassed into doing so, while these people B’derech Teva have no possibility of taking care of their children, so what would be the point of embarassing them!
In the meantime, we are losing those who refuse to pay higher tuition costs due to them subsidizing others (the parents are sending to public school where they may go off, CV) and the children who have a much better chance (if not as good as in BY) in public school (like those girls from BYOBP) are being cried over. Cry for those who are being lost, not those who are not.
