So : With a whole universe of possibilities as answers to this question : All you can do is think of yourself?
What if you could do a far greater good in defining what you'd do if you could do something that is illegal but you could get away with it without anyone knowing what you did? Far greater than just taking care of your "fun dream" of having money to travel and "see needy and do good things with."
Again: Who are these "needy"? Are you just giving your sense of morality a very quick fix here to justify what is basically your greed? Sure : You don't want much. Yeah. Neither do I. And I'm not that much younger than you. But I gotta work for a living. And I couldn't live with myself living on money I'd stolen - from anyone. Even if I knew no one would find out. Of course, though, I would steal from myself..... And I have....... But then, all who know me know I did that.
You're implying, too, that the biggest casino nowadays is connected with illegal gambling. I'm not sure about that. A lot of casinos nowadays are connected with Indian Reservations and this country's indigenous nations, and of preserving a way of living and looking at life that our boorish ancestors all but destroyed in creating this "free" nation with "liberty and justice for all."
Might you want to think a little harder what your answer would be?
