As much as I'd like to see big tech die, and bazinga billionaires to lose money, I'm afraid of what a market crash would do to regular people. Lots of pension funds and retirement savings are tied up in the stock market.
The very rich always find a way to come out of market turmoil with a larger share of the wealth, even if the total wealth is smaller. That'll be another opportunity to do layoffs to "discipline the labor market" and jack up prices, and the working class will once again pay the price for the hubris of the rich.
There were people going crazy for this in that unveiling clip I saw posted here. One dude yelled, "Fuck yeah" and another was going, "What is that?!?", like he was personally meeting Jesus. Made me sick.
