The Hydraulic Theory of the Euro

Jean-Baptiste Queru  recently posted what I call the "Hydraulic Theory" of currency union.  Other than an overall theme of "Blame Germany", it's somewhat discombobulated, but I think the basic point is: The core mechanism that allows multiple states to share the same currency is pretty simple: since  the weaker states can't devalue their currency  to compensate for their trade deficit with the stronger ones,  money has to flow from the stronger economies to the weaker ones  in order to maintain the balance.

They've made lots of loans, but mainly so that Greece could pay back its debt to sha
