Have Westerners ever thought of working and creating real value instead of betting on the death of little children?

Prediction markets are just fine IF they have some means of regulation against insider trading and perverse incentives. This phase is the same thing derivatives markets looked like before the 2008 crisis and Dodd-Frank, and several other waves before that of crisis and reform (Securities Act, Market Reform Act). Every new financial medium gets its moment in the sun when all the crooks extract everything they can, bef…

Just because a rule was created after something bad happened doesn't mean that the rule is effective to prevent it from happening again. The most common result when they try to ban something without removing the incentive fo…
This is true in theory, but in practice the impact of any regular individual's actions on a company is probably going to be small and uncertain enough that it's difficult to make a healthy and reliable profit from. Even the very extreme example of murdering the United Healthcare CEO seems to have caused the stock to drop ~16.5% (assuming the drop is entirely due to the murder). That's like placing a bet with ~1/6 odds. You'd need to short a lot of stock to make that worth the risk of murdering someone (leaving aside any moral issues obviously). You could use leverage to juice those returns but that is expensive and risky, too. If you can afford to deploy enough leverage to make it worth it, you can probably find ways to make money that don't carry a risk of the death penalty.
I guess viewed in this way a bet on a prediction market is like a very cheap, highly leveraged bet on a specific outcome. So the incentives are much stronger as the potential reward for the risk taken is greater.

I can't believe people are throwing so much money on zero/negative sum games that on average have no benefit to anyone including yourself. I mean I know gambling is a thing but at least we are counting that as an addiction. But we seem to take polymarket more seriously.
There is a class of prediction markets that are useful and seem immune to most of these problems : play money prediction markets. I've been enjoying them for years; I feel they provide a useful service to understand what is going on in the world, and they don't seem to provide the perverse incentives that we are seeing here. Oh, and they seem to work just as well.

Why?
If a prediction market is supposed to predict it makes no sense to exclude the best informed people. If I want to know the risk of a Boeing airliner crashing this year, Boeing insiders have much more to contribute than armchair observers.
And if a Boeing insider sabotages a plane to profit on a prediction market - that's illegal. If they're willing to break the law on sabotaging planes, they're surely also willing to break the law on insider trading at the same time. If we think this is a realistic risk, prediction markets should be banned entirely.
Only reason to exclude insiders is if the real purpose of a prediction market is recreational gambling.
Here's one story about gambling in the UK: the TV advertising is relentless and out of control after 9pm due to legislation passed in the early 00s. Gambling can quite literally lose you your house, friends and family. But apparently it's totally fine to advertise as long as HMRC get ££££. On some TV channels, every second advert, or worse, most adverts, are gambling. Bingo? Slots? Poker? Sports? All of the above.
The biggest UK tax payer for several years was Denise Coates.
Tobacco advertising, on the other hand, is totally banned in the UK, but won't lose you your house or family and friends (unless of course you die).
Betting on sport is kind of what sports where made for. It's something without any consequence or meaning. The Author mixing that with the dictator and his cronies making buck from their position is offensive.
What?! Beg I your pardon, but I think sport is a very different thing to me.

I have mixed feelings being a parent now. It can be fun to get a mystery box or pack. But it does feed on the anticipation and rush of surprise. Kids seem to lack the self control to stop. Video games seem the worst to me since they're so intangible it's easier to get carried away before others notice.
I feel so guilty about how often I begged my parents for new magic, Star Wars ccg, or battletech booster packs.

There is genuine value in a wisdom of the crowds assessment of future events that is only sharpened up by the requirement to put money on the line.
