Some will live in the lap of luxury: The Nevada Company that is backing them will get around 50% of the money off the top.
And many tribes "decide" that only a few of the full blooded members of the tribe are actually members.
In one case here in California, a tribe has about 200 people in it, and there are less than a dozen that are "certified" so they get all the money.
Business as usual except for the town's people that have to dodge drunken drivers and those that can't end up with a mangled car.
I just do not see the logic in the move to have casinos established. Really, what does it bring to a community, besides a bunch of losers, for we all know winning at gambling is about as rare as getting struck by lightning. So why don't I see people outside waving a golf iron in the air? They certainly would save a lot of money trying to get hit by lightning instead of dumping their paychecks into casino coffers.
