Interesting speculation Oracle. Low taxes to attract companies certainly help business. I'm yet to be convinced that it's good for citizens.

Whenever anyone uses this argument about disparate economies, I'm reminded of the US economy. There they have states will lots of different laws to each other and very different economic circumstances. Yet they have one currency. I'm not hearing a clamour of people saying Alabama (for example) should leave the dollar to devalue its way out of debt. And yet people are proposing it as a solution to the woes of some Southern European countries.
