So, we're about to have Great Depression 2 and WW3? Fun.
It has felt inevitable to me for a few years now. The market != the economy but a major crash can still trigger a credit crunch that will materially affect regular people. Look at the insane valuations on some of these companies. They can't continue forever.
As for WW3, well, there's a diaper-wearing senile old man, with an inferiority complex to boot, in charge of a nuclear arsenal and major conventional forces.
Sometimes I wish Strauss–Howe theory hadn't been hijacked. It seems noteworthy how similar (cyclical?) things are even if it's a coincidence..
