UJM is making a good point but the question still stands. Do you really think that most families are earning a total of $150k per family? (This is the figure that several authors have posted a frum family needs to get by)
It would seem that UJM’s observation would seem to be correct. Homes are built more luxurious than in the general public, stores in Jewish areas charge top dollar for products (clothing stores, baby items, take-out food establishments etc.), excess income to support married children, lavish weddings etc.
Is it true that only a few poor shnooks are the ones struggling to get by (and the “haves” are generously supporting the “have-nots)?
