Hashemisreading: Really untrue. For one thing, it depends where you’re opening. If you’re opening in Wesley Hills or Pomona, you can (and probably, practically speaking, will) do great while never seeing a chassid in your store. For another thing, even in a store in the middle of 59, there are PLENTY of non-chassidim. The growing of one community to, perhaps, a majority (I haven’t seen demographic information recently) does not mean that the other community is shrinking. There are very much enough non-chassidim to, in theory, be sole supporters of a business.
I’m a second-generation Monsey resident, from a family here long before the chassidim came (not counting NS), and the whole community has exploded over the past 20-some-odd years, not just the chassidim, however huge their population growth may have been specifically.
