Is it for us to tell the goyim what to do? Gambling is not prohibited to goyim by halacha (whereas having the government engage fund raising through piracy, or running brothels, or sponsoring “fight to the death” gladiator competitions would be an halachic issue since they violate the laws governing goyim). Any revenue to the government that we don’t contribute is good for us, since the alternative is to raise taxes on everyone including us.
And at least its more honest than recruiting American Indians, whose ancestors were victims of “ethnic cleansing” and forced expulsions by New York 200+ years, in the hopes do the dirty work the state needs for money (the Indians who were offered reservations if they would run casinos, have a much higher sense of pride and morality, said they weren’t interested, and that we should have thought of that before stealing their land and chasing them away). So it is more logical for the state to legalize casinos rather than trying to evade the state law by recruiting Indians to run them.
P.S. Unlike Connecticut, where the Indians running casinos were always living there – the Indians who lived in the Catskills were evicted under conditions that today would be considered crimes against humanity. New York been trying to get their descendants to move back.
