We will not achieve the understanding we need, however, unless we are willing to think clearly about our problems and to follow those thoughts wherev… - Paul Krugman

Whose fault is the replacement of serious discussion of world trade by what I have come to think of as "pop internationalism"? To some extent, of course, it is the result of basic human instincts: intellectual laziness, even among those who would be seen as wise and deep, will always be a powerful force. To some extent it also reflects the decline in the influence of economists in general: the high prestige of the profession a generation ago had much to do with the presumed effectiveness of Keynesian macroeconomic policies, and has suffered greatly as macroeconomics has dissolved into squabbling factions. And one should not ignore the role of editors, who often prefer what pop internationalists have to say to the disturbingly difficult ideas of people who know how to read national accounts or understand that the trade balance is also the difference between savings and investment. Indeed, some important editors, like James Fallows at The Atlantic or Robert Kuttner at The American Prospect are pop internationalists themselves; they deliberately use their magazines as platforms for what amounts to an anti-intellectual crusade.

Democrats have to figure out why the white working class just voted overwhelmingly against its own economic interests, not pretend that a bit more populism would solve the problem.

The appeal to the intellectually insecure is also more important than it might seem. Because economics touches so much of life, everyone wants to have an opinion. Yet the kind of economics covered in the textbooks is a technical subject that many people find hard to follow. How reassuring, then, to be told that it is all irrelevant -- that all you really need to know are a few simple ideas! Quite a few supply-siders have created for themselves a wonderful alternative intellectual history in which John Maynard Keynes was a fraud, Paul Samuelson and even Milton Friedman are fools, and the true line of deep economic thought runs from Adam Smith through obscure turn-of-the-century Austrians straight to them.
