My theory is that we are simply too wealthy. For the average rich person (the top 20-30%), the first $70,000 goes to real companies who sell real things for money. Past that and it all is just kinda funny money. In our society there are actually a ton of people making this kind of money, so there's just this huge chunk of money that isn't really tied to anything real. If you lose $100k on cryptocurrency, or you spend $800 on some metaverse thing, it's fine, you can still buy food.
Of course this is also why people who don't make this kind of money are so baffled (and angry). Hearing that some no product company [1] was sold for billions of dollars feels insane when you're seriously considering the difference between a $5000 and a $6000 car.
