From Prime Minister Jean-Claude Juncker of Luxembourg, explaining why it's so hard to fix the euromess:
We all know what to do, but we don’t know how to get reelected once we have done it.
That's from Jared Bernstein. More at the link.
UPDATE: This quote is actually from 2005 and has nothing to do with the current crisis. I'm not sure why Jared made it sound like Juncker said it last week, but in any case, I suppose it never hurts to recycle a good quote.
