The irony is that the Jewish population has grown rapidly in Brooklyn and the communities expanding as the other “white ethnics”
die off. High Orthodox birth rates (and not just the Hasidim) and commitment to the community ties are the reason. Gravesend in southern Brooklyn is a case in point. It was once ethnically and religiously mixed, and was an extension of Bensonhurst culturally. Now it is one of the wealthiest communities in the city and largely populated by Syrian Jews.
God Bless the Hasidics. They know what life is all about.
True about the Jews. They cherry pick a neighborhood for expansion as they are growing. Sonetimes they lose. They tried Ridgewood, offering cash butouts but the old German and Italians resisted. A few tried subterfuge. One buyer sent guys dressed as UPS with packages the owners had to sign for. The invoice was actually a quitclaim deed. Couple of Hasidim went to jail. Now the hipsters are moving in. But they rent, have no kids, and move on in a year or two replaced by others. They mostly party in their craft beer bars or take the L train into the city so the old timers are happy for the rent.
