Earlier quoted context omitted.
Gambling legalization historically happens in waves following economic downturns because society’s tolerance for exploitation increases. It’s fundamentally a regressive tax that healthy societies won’t tolerate.
Is it tolerance for exploitation or are people just realizing that as poor as their odds are while gambling that's still the best chance they have to make the money they need. A healthy society offers the public better ways to have their needs meet, people gamble when they are desperate.
It's a stretch to say that gambling is truly anyone's best option, so 'realizing' isn't the right word here. I'd go with "delusionalizing."
