I think the markets prove the point. People don’t sell houses for $750,000-$1,000,000 unless there are likely buyers. Pesach programs don’t open up unless they have likely customers. Jewish clothing stores do not charge 3-4 times the price as the rest of the market unless they have regular customers, women would not take on jobs as party planners unless there was a demand for it, leasing companies serving the frum community would not be offering as many cars as they do unless they had customers. New seminaries would not be opening every year unless there was a demand for them, fast food joints etc…..
You can stick your head in the sand but these businesses seemed to have been flourishing and increasing before corona hit.
