The crash does not come without warnings, if you know where to look for them.

Economic crashes appear to strike without warning. That's only the case when you follow central banks and Economists who time and time again refuse to consider an entire array of dependable, useful, and most of all timely warnings. While having such knowledge won't alter the economy's course, we can (and should) be prepared for what happens. It is never "unexpected", so get out of the car driven by blind officials.
