Why do primary/first/second grade girls have a morah + 1/2 assistants, while boys rebbeim have to handle 25+ rambunctious/ difficult/ behavior issues etc boys single handed??!?
I'm a little late to this discussion, but in addition to the points mentioned above, which I mostly agree with, keep in mind that the rebbi in that classroom is probably being paid at least double what the girls' teacher is. Wage discrimination is alive and well in our community.
