I fully agree with not participating and would go even further: it's far worse than a casino, which was already bad. It's not regulated. It has a stronger impact on the outside world. With bets you can put a target on people job or head.

You say that like it's bad thing, but really it's great!

It gives us normies a way to see what the powerful are thinking.

Except, the thing is, a decent portion of the population enjoys throwing money away in casinos. If they feel a similar level of enjoyment/entertainment from this type of market, then it's no different and they're playing for a non-financial purpose that your calculus isn't pricing in. Maybe a stretch but theoretically, if they enjoy it enough, it can serve as a much cheaper alternative to a casino and thus could actually have a positive net return to one's personal finances even while losing.

And, I'm not even contemplating gambling addiction. There's a huge market of people that just go to Vegas once or twice a year and come home thousands of dollars poorer. But they don't need it, they may not gamble outside of Vegas, or nothing that would signal an addiction.
