Rosenberg Research has only been around since 2020 as well. Dude had a long career before that working as a chief economist for Merrill Lynch though. He probably has insight most others don't. I'd be curious how his stock purchases align to his doom casting though. I wonder if he actually practices what he preaches.
A crash just lets the capitalists buy up more for nothing with their shameful human exploitation hoards from their last trip to the value extraction casino.
More for the capitalists and less for everybody else. That is humanity's current driving force in practice.
The capitalist's cruelty and the rest of humanity's deluded acceptance of it really makes climate change look more like salvation than damnation. At best, pain might wake the masses up when their meager subsistence opiates dry up, and at worst, extinction is better than the dominion of cruel sociopaths exploiting and propandizing their own species to self-flagellate for them in perpetuity.
We don't need another crash sale for them, we need collapse. We need the paper they hoard as symbols or power to be of more value as kindling. This civilization isn't repairable. "But people will suffer!" People are suffering, go to your nearest homeless city in your nearest population center if you believe otherwise, and suffering without hope or end as long as this global economy exists and has its tentacles capturing every world government to serve the capitalists at all other's expense. At least collapse would bring faint hope for a better world that no rational person could have today.
