The Lump of Labor

Sometimes I stumble across recitations of the lump of labor catechism that I missed at the time. Here's one that's untimeliness has become timely by the juxtaposition of the 2003 Bloomberg column to an advertisement for a current Bloomberg feature: "Lump-of-Labour Fallacy Gussied Up for a New Era" and "Flying Robots"! Ms. Baum bills herself on twitter as "a Bloomberg View columnist, writing about the macro-economy and the intersection beween [sic] politics and economics.

Why on earth would you need a government bureaucrat telling you to do you what is good for you? How likely is it that you don't know how to achieve a productivity gain in your business, while some distant bureaucrat does know?" Evidence? Of course I don't provide evidence. Why on earth would we need evidence? It is self-evident. I don't have to show you any stinkin' evidence! Sir Sydney J. Chapman: "The reforming employer would run
