"You never let a serious crisis go to waste. And what I mean by that it's an opportunity to do things you think you could not do before." -Rahm Emanuel
That, I'm afraid, is exactly what will happen when (not if) the next major economic crisis hits. I'd even venture to guess it's Rule No. 1 in the "central planners" rulebook.
Major new laws like FATCA (Foreign Account Tax Compliance Act) and a growing acceptance by major governments of a digital currency, like Bitcoin, are simply setting the stage.
The ultimate goal is to establish and roll out a single, planetary currency regime. There will, quite simply, be no alternative available.
It's all about control.
