:::Per "[k]eep sell-sourced":  the Becker quote in question is demonstrably a statement made by Becker and Becker is a Nobel Prize-winner in Economic Science.  If you are asserting that the quote is less-than-well sourced, would you please specify deficiencies supporting the claim?    

 :::Per 'Krugman's column is self described as "politics"'.  What is the saliency of that observation?   the Wikipedia article in question is "Paul Krugman" not "Paul Krugman's Column".
