Look at the average salary of a Chassidic Jews vs Average Salary of a Yeshivish jew vs the average salary of a MO Jew many who have college degrees and advanced degrees.
Yes the Chassidim work, but they dont usually work (Unless its Diamonds) in High paying jobs that are needed to support a Frum Lifestyle . IE 10 Yeshiva Tuitions, Kosher Food costs more, Cost of Living in Jewish Neighborhoods cost more
