@AvirahDeArah Don’t pick on one aspect of my comment and ignore the rest. I addressed your questions, now you address mine. I only brought up “Horeb” as an example of a non-Gemara curriculum that Yeshivos can follow (notably, it doesn’t mention teaching your kids to choose their own pronouns).
Satmar, to their credit, encourage their Chassidim to learn business and go into it. (The same cannot be said of many other Yeshivish and Chassidishe communities.) I’ve heard once that if the Rebbe ZT”L would have agreed with Rav JB Soleveitchik ZT”L on one thing, it was kollel. The big Satmar companies, however, are still just yechidim. A few hundred successes in a sea of tens of thousands. And of those tens of thousands, many have reportable income far below poverty level. I think something like nearly half of all Palm Tree residents are on Welfare and Food Stamps, which is far far above national average. You cannot point to a handful of nursing homes and mortgage brokers and say “Well it obviously works” when on the other side you have that.
