So the fiscal controls that were designed to prevent eurozone countries from running big government deficits didn't work, partly because investment banks helped governments to hide the debts they were running up. So now the plan is to introduce tighter, more supervised, fiscal controls and hope that they work.
But what I don't really understand is why the euro couldn't have been set up much more loosely. If a country goes bust then that's its problem. If it has a big trade deficit then it can use up its currency reserves and then that's it, it will have to stop importing until it's sold some more exports. That doesn't mean an end to the single currency. So why didn't it work out like that? Why did Germany allow itself to get into the situation where the government and banks had lent so much to Greece that the government had to keep lending more in order to protect its banks? I'm not sure that I get it.
