Maybe, but does he? Paul Krugman's current job description is as an international fixer of bad economic policy, a consultant. He apparently helped steer the Eurozone out of recession. So the answer is another question - does he read with comprehension? To a five-year-old, adult discussion sounds like the quacking of ducks. Krugman picks a different topic twice a week for his columns. If they seem the same, it's a reader incomprehension problem. The reader needs to try harder.
