Dr Alf is right about Krugman, the truth is most Americans are deeply conservative, follow Judeo Christian thinking and believe in self reliance ,pulling yourself up by your bootstraps and “No free lunch”.
The metropolitan elites from which people like Krugman has emerged believe in their own rightness and intellectual superiority and are therefore keener to favour politicians who court the most disadvantaged groups.
The prevailing majority philosophy is the right one because it is the one which goes with the grain of human nature and is one that says that we are free to make our own choices and as far as possible shape our own lives.
The Pastrami sandwich analogy is a double edged sword because those who eat them wearing their bankers suits or NYSE uniforms might well be Americans but their liberal values and anything goes philosophy does not make for stable traditional marriage, family life or global competitiveness.
America’s rivals in the Far East know that which is one of the reasons they are “Eating the West’s lunch”. The American politician who taps into that best and can deliver is the one who deserves to win because he /she is best positioned to help everyone in America not just the Pastrami eaters and the poor.
