In the last few days, a rhetorical fight is going on between two liberal NYTimes columnists Paul Krugman and Nick Kristof on the latest book of Charles Murray that finds that personal social status (marriage) and morality is tied with economic mobility and wages. They fight weather low morality is the cause of low wages or low wages are the cause of low morality. Very interesting discussion, worth to give a look in both, their column and blog. Thoughts?
