It should be possible to emphasize to students that the level of employment is a macroeconomic issue, depending in the short run on aggregate demand and depending in the long run on the natural rate of unemployment, with microeconomic policies like tariffs having little net effect. Trade policy should be debated in terms of its impact on efficiency, not in terms of phoney numbers about jobs created or lost.
Paul KrugmanYes, over the centuries economic progress has reduced some gross disparities - modern Americans are relatively unlikely to simply starve to death (though it can happen), so in that sense the gap between rich and poor has narrowed. But the question isn't whether society is, in some sense, more equal than it was in 1900. It's whether it is radically more unequal than it was in 1970. And of course it is.
Paul KrugmanI think if you're a liberal, you believe that we all are, at least to some extent, our brothers' keepers, you really believe that we have a sumptuary responsibility to make sure that life is decent for everybody in America, that you believe that society out to be broadly shared, and you believe that you can't have a real democracy unless you have a little bit, at least, of economic democracy.
