The fact is, despite all the nonsense we heard during the Bubble about the “new economy,” there was a core of truth. You need that to get a really big bubble: you need to have something solid at the center, so that even smart people are sucked in. (Isaac Newton and Jonathan Swift both lost money in the South Sea Bubble of 1720.)
Now the pendulum has swung the other way. Now anything that became fashionable during the Bubble is ipso facto unfashionable. But that’s a mistake– an even bigger mistake than believing what everyone was saying in 1999. Over the long term, what the Bubble got right will be more important than what it got wrong.
