Henry comments in The Australian (30 April 2010)

MILTON Friedman was notoriously sceptical of the euro, predicting it was "going to be a big source of problems, not a source of help". When crisis hit, monetary union would prevent the eurozone countries from adopting solutions tailored to their individual circumstances.
