“If you want a simple model for predicting the unemployment rate in the United States over the next few years, here it is: It will be what [Alan] Greenspan wants it to be, plus or minus a random error reflecting the fact that he is not quite God.”

-- Paul Krugman, 1997

Note this does not say "it will decrease if we suddenly invent new productivity technologies".

Jokes on them. You don’t need MBAs any more. You just need the cash or a credit line.
