In a recent column on the Tuition Crisis, Rabbi Yitzchok Adlerstein discussed the strife generated by tuition inequality, including the following thought a day school parent might have:
If a shul hires a new rov, why should his four children be entitled to any tuition assistance, when it translates into a demand on the baal habos who does not even daven in his shul? Should it not be the responsibility of the shul to pay salaries that will allow the rov to pay his tuition obligation without thrusting him upon a small group from whom it is demanded that they foot the bill?
For the record: I don't think schools should offer shul rabbis (or community rabbis) automatic tuition assistance. Certainly, the rabbi helps the school. And certainly, the rabbi is there to serve the community. Nonetheless, the school is providing the great service of educating the rabbi's children, and the rabbi should pay them for it, just as others do.
