with all the hocking aside
Our Gedolim have many times said and cried out in public that much of the problem of kids at risk etc lays in the fact that our classes are overfull, yes the average class in the chasidic schools in Lakewood is over 27 kids per class, so now lets do the math, lets say there are 20 kids to place,
There is Satmar (one class per grade,mesoras avos (one class per grade), Bais avroham (3 classes per grade),Toras emes (one class per grade)Rachmistrivk (one class per grade)Rav Wosners cheder (one class per grade)
A total of 6 schools,and 8 classes
if you were to place another 2 or more kids per class you will have 29 kids per a class!
i would not want to teach or have my child in a class of 29 kids
WADR, I think there are more than 6 schools in Lakewood (although I am not sure). In addition, you (and the teachers) may not have that choice (to not have 29 children in a class). YOU can always open a new school, if you don’t like it, and the Rabbaim can leave/quit.
Finally, you did not answer why you can not open a new school in someone’s home.
