Over a period of 20 years, German reunification has cost 2 trillion euros, or an average of 100 billion euros a year. So, we have to ask ourselves: Aren't we willing to pay a tenth of that over several years for Europe's unity?

There's no more place in the euro zone for well-meaning laxness when dealing with deficits and failings. If the demands on Greece aren't taken seriously, we'll get stuck in quicksand. In the worst case, this would make it acceptable for one tranche to not be paid out. It is in the Greeks own interest not to test that.

Leverage is great when it works, and when it doesn't work, it creates a lot of issues. So I think if you limit the amount of leverage that people can borrow, or that banks can borrow, I think you'll find that you'll have a lot less issues going forward.
