In fact very often even secular education of chasidishe yeshivos /schools surpass those of the public school system.
Whoopie! !@#$%^& unions are in charge of public schools.
As a side point, the 3800 doesn’t include all of the voucher monies gotten from the city/state for “After school care” which goes straight to tuition. That is why there was such an uproar when Bloomberg wanted to cut Priority 7 vouchers, all the “low tuition” schools are living off of it. That’s not even bringing in the schools that have official “CONTRACTED CHILD CARE” from the city, but (I imagine) always seem to be full when someone outside wants to join.
