An article in Slate lists some of history's all-time worst "bubble-blowers" -- people who help create unsustainable economic bubbles through their relentless promotion, over-optimism, and snake-oil salesmanship. Upon seeing the article, my first thought was, I bet I know at least one person who will definitely make the list. I was right:
George Gilder (1939-present)
Noteworthy bubble-blowing role: Newsletter writer and futurist foresaw a world of infinite wealth because of infinite bandwidth. Book published in 2000 promoted soon-to-be-worthless stocks like WorldCom and Global Crossing.
Catchphrase: "The investor who never acts until the financials affirm his choice is doomed to mediocrity by trust in spurious rationality."
Bonus catchphrase: Of WorldCom CEO Bernie Ebbers, he said: "He is a hero of the dimensions of Rockefeller and Milken."
