A popular topic in the blogosphere, given new life after comments by Nobel prize winning economist Paul Krugman, is the relative success of the United States vs. the states that make up the European Union. The European Union is a loose confederation of 27 countries in Europe, ranging from Spain to Estonia. Krugman goes so far to suggest that "[y]ou should always bear in mind that when the question is which to believe — official economic statistics or your own lying eyes — the eyes have it."
