No, where we went wrong was your saying the Fed's logic was 'sinister' -- i.e., satanic. That's a bit of a hyperbole. I was poking fun at your blaming the devil.
Words mean things, so another thought is that while the US economy still does the work of a fourth of the world's population, it's only got a twentieth of the worlds people. Some "house of cards".
That's not what sinister means (the root is from the latin word for unlucky or ominous, and has nothing to do with "the devil").
