The industry makes nearly all it's money from problem gamblers.

Know that these companies internally have models to predict how profitable you will be as a customer, so that they can best nudge those customers who are likely to be profitable.

This model is identical to if you trained a model explicitly to find problem gamblers. They are purposely building systems to find and exploit problem gamblers.

Because that is what the industry does. It finds and milks addicts. It is impossible for a for profit company to exist in this space and not somehow optimize towards finding and exploiting addicts. It's just more profitable. The people who drop a few hundred on a few hands of blackjack once a year cannot sustain an industry.

Extracting all possible wealth from 20% of the significant fraction of the population that plays has enormous negative consequences for all of society.

The only reason you don't ban gambling outright is that it's just too easy and straightforward to run an underground book, so it's a trivial market for organized crime to own. And that isn't good.

So you should have a state run institution that exists entirely to just barely serve the literal addicts, does absolutely nothing with the "income" (preferably just pays it all out, zero sum), and is rather unattractive to people who haven't gambled before. You make betting as boring as possible.

Those push notifications are tuned to trigger someone who might become a problem gambler. They are actively trying to get you addicted.
