I like your joke and my Subject is the one I was looking for in the discussion. Just more "tools for fools" to help the richer get more obscenely rich.
I'll add the horse race joke, since I'm pretty sure it also applies here, even though I'm basically too contemptuous of all gambling to spend time digging out the details for the polymarkets. However I'm pretty sure this is one of the scams where the house takes profits off the top. Therefore there are two cases for the gamblers. They might believe the game is honest and they therefore know they are going to lose if they play long enough. Or they believe the game is crooked and they think they can cheat better than the other suckers, which is still a sucker's bet if they stick at it long enough to lose against a better cheater. This path to losing includes getting old and slow or missing new techniques of cheating.
Classic joke: Gambling is a special tax on people who are bad at math.
Citation? Sorry, I don't remember the book, but it was about training primates to gamble. They love it, but if I remember correctly it was the younger adult males that would make the biggest bets.
