I wonder if there is a long game strategy to undermine the yeshivos that lay hidden behind the idea of compulsory education.
A yeshiva with a staff for secular studies is twice the budget, or the MO dayschool model.
MO folks have to get very involved jobs and commonly both spouses have to work to be able to pay for these schools. Typically these neighborhoods are very pricey too so professional status precedes everything in life.
Sadly MO is emphasizing Derech Eretz a lot more than Torah, for the sake of necessity at this point. I’m watching it happen to a Shul nearby where every young family is working themselves into the ground trying to make ends meet and always looking to move somewhere less expensive. Look a Boston, it’s MO community is shelled out because of this very problem. Multiple MO Shula there only have lingering aging communities left because the younger crowd left, became more frum or fried out.
Mandatory secular studies being foisted upon all yeshivos would create this same problem for the chassidishe crowd, if they complied at all. I really wonder if that is the long game in these efforts.
