I agree that company fundamentals don't matter, and that the goal right now seems to be techno-feudalism.
Retail is ~40% of the stock market, and retirement is ~20%. I think it will pop whenever the next recession starts. If enough people lose their jobs, and start selling their stocks and dipping into their retirement to pay bills, these stocks will tank. It's my theory that these stocks are held up by all the people passively investing in index funds following the SP500 and NASDAQ. During any small sell-off by active investors, a lot of people's retirement plans will eventually automatically just buy and slowly bring it back up.
A scare, widely reported by media, could also cause people to take enough notice where a lot of people manually adjust their plans. But, yeah, the media is pretty captured now, and will avoid reporting on stuff that could cause scares.
If you consider the Zapatista's anarchist, they are a federation of autonomous municipalities that do stuff like this (along with hospitals, schools, etc).
