We must be talking at odds here. I'm neither claiming that being ethical is a sufficient condition to getting rich, nor that the ethics of the poor people described in the article played a significant part in their being and remaining poor. The article seems replete with unethical behavior at every level of wealth.

My point is that people with high time preference and low impulse control, who naturally will tend to be poorer than people without those traits, will also naturally be more drawn to the "lottery economy", whether or not bad actors exist who will take advantage of that. Just look at who buys literal lottery tickets!
The people who are behind this scam chose the east side of N.O. because poor people are desperate, not cause they have bad judgement. They could have found other people but why bother?
