The Euro Trap link
.../ To understand the euro-mess — and its lessons for the rest of us — you need to see past the headlines. Right now everyone is focused on public debt, which can make it seem as if this is a simple story of governments that couldn’t control their spending. But that’s only part of the story for Greece, much less for Portugal, and not at all the story for Spain. (...)

What’s the nature of the trap? During the years of easy money, wages and prices in the crisis countries rose much faster than in the rest of Europe. Now that the money is no longer rolling in, those countries need to get costs back in line. (...)

So is the euro itself in danger? In a word, yes. If European leaders don’t start acting much more forcefully, providing Greece with enough help to avoid the worst, a chain reaction that starts with a Greek default and ends up wreaking much wider havoc looks all too possible.
Meanwhile, what are the lessons for the rest of us?
The deficit hawks are already trying to appropriate the European crisis, presenting it as an object lesson in the evils of government red ink. What the crisis really demonstrates, however, is the dangers of putting yourself in a policy straitjacket. When they joined the euro, the governments of Greece, Portugal and Spain denied themselves the ability to do some bad things, like printing too much money; but they also denied themselves the ability to respond flexibly to events.
And when crisis strikes, governments need to be able to act. That’s what the architects of the euro forgot — and the rest of us need to remember.
