I (in general) view yeshiva like any business, in which there is professional courtesy that is not based on need. SJS is correct that it presumes the owner is turning a sufficent profit. If there is no profit (such as most if not all yeshivos) I hear cutting out professional courtesy.
I actually think tuition breaks should be based on willingness to send to yeshiva (worth of the education), that those who would send to public school should pay less (in order to keep their children in yeshiva) than those who would never do so (and therefore will pay or raise whatever is asked of them). That would be a different and new thread, as well as too radical to implement.
