Given enough effort – the whole 10,000 hours thing – most people can perform most tasks fairly competently. Excellence? Well, that’s a bit different. Here is Paul Krugman showing Amity Shlaes how many places there are to run:
[W]ith short-term interest rates near zero, there’s no reason to think that lower wages for all workers — as opposed to lower wages for a particular group of workers — would lead to higher employment.
Suppose that wages across the US economy had been, say, 20 percent lower than they actually were. You might be tempted to say that this would make hiring workers more attractive. But to a first approximation, prices would also have been 20 percent lower — so the real wage would not have been reduced. So how would lower wages lead to higher demand for labor?

Andrew Mellon’s advice to Hoover during the Depression – “Liquidate labor, liquidate stocks, liquidate the farmers, liquidate real estate . . . purge the rottenness out of the system” – has intuitive appeal. That doesn’t make it right, however.
