With Casino gambling legal almost everywhere Las Vegas had to re-invent itself and now over 50% of its revenues are from non-casino sources.
Atlantic City is also trying to reinvent itself the same. You actually need more activies than gambling to be successful.
The fact of the matter is Sullivan County is an economically depressed area and they need tax revenues and jobs there. At one time when the Borscht Belt was huge people would go, now only Charedi jews go there and then only for 2 months.
All the anti-casino arguments would hold true if it wasnt generally legal. But its legal most places now, might as well keep the jobs and tax revenue here
And BTW quite a few jews have made huge fortunes from Casinos Dr Irwin Moskowitz and Sheldon Adelson both of whom I think give alot of Tzedkah
