Wow - tough question. I see a few very good articles here and there, and always study various facts. And then you make conclusions. There are also economists who study these topics but very very few because as I explained Part 3 - in Economics it is a TABOO to speak about "End of Capitalism" crisis.....
FOr example at my work (finance sector) I can not say "Hey Guys, lets sell all our assets because the world will end tomorrow". Instead, we need to say that it is a recovery path, assume like 1-2% growth, because we raised money from the investors (and we pay for this money), and this money needs to be deployed !
