We need to consolidate long term and somehow find a way for earth to support 10 billion people, and maybe stop making babies in poor countries yo? There isn't infinite space here there isn't infinite water, isn't infinite arable land.
Going to take a whole while... We have went up too fast for our own good.
(If you ask me we have no went too fast it's just that the smartest on the planet have gone at their pace inventing great things and Cletus Brandine over here have a hard time catching up with their 10 babies chemtrail conspiracy videos crypto investments heavy weight on the medical system overconsumption of cheap caloric foods overuse of oil because too lazy to walk & now we have to wait for them, pulling humanity down zzz).
Still, the ones that are good, will be able to make money trading/investing.
There just won't be any billionaire buying and holding and sitting on his ass telling people to "just buy the indice" (no disrespect).
And some other stock markets might have some big gains to make, but the planet in general will slow down.
