Or, being needy, have been crapped on by institutions multiple times and have a fatalistic view. Well, it was fun while it lasted, or guess I need to get a job and spend time working to complete my education. It is amazing how many problems could be resolved by a talk with a school administrator that doesn't because students just accept what they are told.
I need to see data based on the same environment and economic situation to believe that line. Rich is rich. Frankly, saying "white people are taught to complain to authority figures" is a gross generalization and untrue with specific groups in this country. Many whites are taught to respect authority figures and not question them.
Oh, and poor people don't assume they don't understand the system. They assume that they understand it all too well and it just isn't interested in their success and that crosses racial lines rather painfully.
He could've played a table game like Blackjack, but he would've been subjected the scrutiny of a human dealer.
He could've used smaller denominations, but the reward may not have been worth the effort.
But as you said, he used them and the machine malfunctioned (not his fault). When he walked away from a pile of money, they immediately knew he was the culprit.
That's reminiscent of what gave away Louis Colavecchio, who was ripping off Atlantic City casinos with counterfeit tokens. The casinos knew they were being ripped off, because their token inventory was higher than they could account for, and the discrepancy was increasing.
The counterfeit tokens were good enough that the casinos had no way to detect them, and when they sent a batch of tokens back to the manufacturer that they were sure include at least some counterfeits and asked if the manufacturer could come up with some way to fight this, the manufacturer said all the tokens were genuine.
What finally happened is that Colavecchio was using his counterfeit tokens at a slot machine that took high value tokens, like $50, and the token mechanism jammed. Colavecchio just moved over to the next machine, and continued playing.
The security people saw this, and found it very suspicious. When a machine jams and eats someone's $50 token, they don't just move over and continue gambling, even if they are a gambling addict. They go find casino staff to retrieve the jammed token or get reimbursed.
They detained him and searched his car and room, and found a large collections of tokens for several casinos, and knew they had finally found the counterfeiter.
