I have every reason to believe this and feel the crisis in 2008 was only a light taste for what is coming.
I disagree with this: the US economy (at least) got slammed, hard, during the banking/housing crisis of 2008-09. Unemployment was rampant for years afterward, and the whole debacle got labeled "the great recession" as a result. I think the world got more than a taste of what a crash looks like, and we're still recovering from that.
Are we due for another one? Maybe. It does seem like there's some trouble every decade or so, when people forget how bad things can get. And I definitely have been waiting for a stock market correction/crash for years now. This is turning out to be one of the strongest bull markets in stocks we've ever seen. I'm realistic and realize that this can't go on forever. It's probably a good thing that stocks like Facebook and Twitter have recently been hammered--that's healthy after a long period of intense speculation.
We are always on route to a financial crisis when the leaders print money at will.
That scares me too, and I think it's one reason why the stock market has been on the run it has. There's so much money chasing stocks when interest rates are near zero. I'm just waiting for the whole house of cards to collapse.
