Prices drop, causing more people to get fired. IE: The Great Depression. Or if you want a modern economy that’s undergoing this shift, just look at China right now.
If people can’t afford things, your only choice is to fire workers and drop prices further. That’s just economics. (Why do you need workers? No one is buying anything, so fire your workers. Duh). The more people realize that this is the only strategy to survive, the lower prices get, the more people get fired, and the less that people can consume. It gets worse and worse until economists change policy and pull you out of this.
This is why we have large pseudo-government central banks keeping watch over our economy. Deflation cannot be tolerated. Yes, inflation sucks, but at least people still have jobs and livelyhoods in times of inflation or hyperinflation even. That’s actually survivable. Deflation is NOT survivable, it sucks so much worse. Deflation is all-hands-on-deck we need to work together kind of situation. We never want to push the economy to that direction.
China isn’t doomed btw. China’s plan is to exports goods to Europe and hope that Europe buys enough Chinese crap that they can kickstart demand again. And as prices drop further and further, Chinese goods will get cheaper, and crap like Temu will pop up to sell these cheaper goods to everyone. Now there’s geopolitical repercussions to this (not everyone will want to support such “dumping” of goods into our countries), so there’s no guarantee that China will be successful on this front.
