GAW:
If the school moved, it would lave the remaining non-Chassidic students with no school, and most can’t afford to move. If they could have afforded moving they would have moved already.
Teachers were always paid peanuts (if they’re lucky they got min wage). Many of my daughters’ friends taught there. Until the Shidduch crisis and more recently the economic situation, forced girls to get higher degrees (Accounting, Speech, OT, PT….), it was considered statusy to be teaching there. It was rumored at one time, that some wealthy parents paid the school, to hire their daughters.
Tuitions are way lower than the norm for schools across America, because family size is larger in Brooklyn… I think the average is quite a bit under 400 a month, with many unable to pay that at the present time.
