Of course, A.F. of L. President Samuel Gompers's advocacy of Chinese Exclusion -- like Donald Trump's proposal for Muslim (and Mexican) Exclusion -- was "not inspired by a scintilla of prejudice of any kind, but with the best interests of our country uppermost in our mind..." Not a scintilla!
Sam Gompers also said, "So long as there is one man who seeks employment and cannot find it, the hours of work are too long." I mention this because both anxiety about immigration and advocacy of shorter working time as a remedy for unemployment have been ridiculed by economists -- including Krugman -- as products of a mistaken "lump-of-labor" belief in a fixed amount of work.
Thanks in part to decades of condescension by economists (including Paul Krugman), the shorter working time remedy is now conveniently "off the agenda." According to Krugman, he doesn’t "get too worked up about this kind of misunderstanding anymore; it doesn’t have political power behind it, the way right-wing fallacies do."
But what about unemployment? "Yes," Krugman conceded in his 1997 hot dogs and buns rebuttal to William Greider, "technological change has led to a shift in the industrial structure of employment. But there has been no net job loss; and there is no reason to expect such a loss in the future." Which could be paraphrased as yes, immigration has led to a shift in the ethnic composition of employment. But there has been no net job loss; and there is no reason to expect such a loss in the future." Here is why we shouldn't have to get worked up about unemployment anymore:
But wait--what entitles me to assume that consumer demand will rise enough to absorb all the additional production? One good answer is: Why not? If production were to double, and all that production were to be sold, then total income would double too; so why wouldn't consumption double? That is, why should there be a shortfall in consumption merely because the economy produces more?
Here again, however, there is a deeper answer. It is possible for economies to suffer from an overall inadequacy of demand -- recessions do happen. However, such slumps are essentially monetary -- they come about because people try in the aggregate to hold more cash than there actually is in circulation. (That insight is the essence of Keynesian economics.) And they can usually be cured by issuing more money -- full stop, end of story. An overall excess of production capacity (compared to what?) has nothing at all to do with it.Full stop. End of story.
Except that's not the end of the story. That insight which Krugman called "the essence of Keynesian economics"? There was more than one application of the principle, according to the man himself:
The full employment policy by means of investment is only one particular application of an intellectual theorem. You can produce the result just as well by consuming more or working less. Personally I regard the investment policy as first aid. In U.S. it almost certainly will not do the trick. Less work is the ultimate solution.In other words, "So long as there is one man who seeks employment and cannot find it, the hours of work are too long." So, what'll be -- meat or rice?
