I love Native American culture, history, and lore.
I look forward to seeing
any of that in the game, since it's not in the game files now.
I think government-supported gambling as a means to raise funds is a cancer on our society. Using addictive and compulsive behavior of certain individuals to enrich a community even if it is for schools, hospitals, roads, etc is an immoral trade off, imo. Gambling destroys families, lives, and engenders misery but the compulsion to do it is what those who open and operate casinos are banking on to make their profits.
I think you are confusing gambling in general, with gambling
addiction. Casinos can make money off of gambling without making money off of the addiction.
But, it's a very thick grey line between the two to be sure.
For what it's worth, Native American tribes also consider this. It's one reason why roughly half the tribes in America do not own casinos. (Native Americans also gamble at those casinos, after all.)
But those which do, are deciding that the social detriments are outweighed by the social benefits. Lack of employment, medicine, education, or social support services
also destroy families, lives, and engenders misery - and that misery is
systematic and generational.
If you have a better way for Native Americans to avoid that misery, I'm sure everyone involved would love to hear it. But so far nothing else has worked.
Also, not that it matters, but I do not approve of people exploiting gambling addiction either. It's one of the reasons I don't want thinks like paid loot boxes anywhere near video games.
EDIT: Also it doesn't much matter to the game, nor the trope, because the negative effects of gambling addiction don't enter into it. The Duke is not "bad" because he caused gambling addiction; that isn't even mentioned. He's "bad" because he's corrupt, greedy, violent, and runs a protection racket.
They also understand that there WILL be a level of illegal and immoral activity associated with the gambling that they are prepared to turn a blind eye to in order to start their business.
Do you have any evidence that the tribes who start casinos turn a blind eye to illegal activity? Or is that just what you think because you don't like gambling?
