The construction of the Euro, George Soros writes, "is patently flawed. A fully fledged currency requires both a central bank and a Treasury. The Treasury need not be used to tax citizens on an everyday basis but it needs to be available in times of crisis. When the financial system is in danger of collapsing, the central bank can provide liquidity, but only a Treasury can deal with problems of solvency. This is a well-known fact that should have been clear to everyone involved in the creation of the euro."
