Yep, orchestrated collapse.
One or more foreign govts hostile to the us can invest a few billion each in the stock market through shell companies and then trigger a drop in the market just like 2008.
Loosing a few billion in the stock market in an attack against the US economy, an economic war, is cheaper than fighting a conventional war they can’t win.
Yet, if the economy of the USA goes down, the whole world will suffer.
