Krugman, as usual, is right. What this piece raises but doesn't quite nail, though, is the emotional locus of both the political rage and the self-help snake oil. Both come out of and speak to low self-esteem, isolation, loneliness. Murdoch and his brethren -- Limbaugh et al. -- saw a market opportunity in monetizing that sadness. They saw a nation of people living lives of quiet desperation -- people who not only lack hope but are socially atomized, who need something to fill the long hours of their days.
