#1-2 are frightening. There is no better way to dilute education than to wreck the ratio of student to teacher. For many years, the invisible cap was 25, and that was a challenge.

If solving a financial problem means cutting back on real chinuch, thanks, but no thanks.
This is absurd as suggesting that you save on tissues by using one only every third time you need to wipe your nose. Get real.
