QUOTE : What Greenspan was saying, in other words, was that there was absolutely nothing wrong with bidding up to $100 million in share value some hot-air Internet stock, because the lack of that company’s “physical value” (i.e., the actual money those three employees weren’t earning) could be overcome by the inherent value of their “ideas.” To say that this was a radical reinterpretation of the entire science of economics is an understatement—economists had never dared measure “value” except in terms of actual concrete production. It was equivalent to a chemist saying that concrete becomes gold when you paint it yellow. It was lunacy.
