Obviously you have rather romantic and idealistic view of how casinos work. When I go to Vegas I often see casinos full of clearly lower middle class crowd wasting away hours on putting in their hard earned cash in slot machines in a hope to win jackpot. Those are the times I am glad I have had some education in math of probabilities and more importantly how powerful tilt rules in their favor.
My view is neither romantic nor idealistic. I understand that casinos do fuck people over, exploit addiction and use numerous tricks to cross the wires of people's (already flawed) internal statistical calculators.
Yes, sometimes casinos will use their political strength to not payout a jackpot (malfunction voids all play), but a player does, in fact, have some recourse if the casino is full of shit.
Regardless, if you're going to a casino intending to win a jackpot, you're doing it wrong (because math). If you take a measured approach and enjoy it for what it is (entertainment, not a way to make money), you'll have a much healthier relationship with a casino.
As an aside, there's another industry that uses it's massive political clout and every trick in the book to refuse to pay in situations where one would intuitively believe one should be payed: insurance.
