Amazon review:
As an economic and political conservative,
this book embarrasses me. Mostly because I might be tarred with guilt by association at the sloppy thinking Lewis demonstrates.
The central paradox of Lewis' book is this: He's all in favor of market outcomes -- just as long as the market agrees with him. Or, to put it another way: If Keynes is wrong, then Lewis is wrong, too, which would make Keynes right. The only way for Lewis to be right is if Keynes is right. That's paradoxical, and Lewis apparently hates paradoxes. That's a shame, because being a human being (and therefore paradoxical), he's written a paradoxical book.
Here's the problem: Lewis presents himself as a classical laissez-faire kind of guy. His main beef with Keynes is Keynes calls for too much government intervention in the marketplace. Lewis, like most laissez-faire believers, bases his assertion on the idea that markets constitute assemblies of rational actors, and thus arrive at the best pricing decisions possible under all circumstances. Keynes believes that economic actors are *usually* rational, but sometimes not. When they're not, government (which, in democracies, is just an alternate assembly of rational actors) needs to lend a nudge.
What no one disputes is that Keynesian ideas are now applied by the overwhelming majority of governments. The trouble for Lewis is, the near universal adoption of Keynesian ideas is itself an outcome of the market. It did not take place in a vacuum, and it did not happen in all countries at the same time. If Lewis is right, and minimally regulated markets outperform Keynesian ones, that should have been obvious over the decades Keynesian ideas took hold. *Some* country (or countries) should have stayed minimally regulated, and made a financial killing. That didn't happen, and it was results-based. Further, if Keynesian doctrines *don't* outperform minimally regulated markets, and the nations of the world individually adopted Keynesian doctrines *anyway*, then that would be an irrational decision -- which would toss the idea of "rational actors" into a cocked hat, and Lewis along the way as collateral damage. And, oh yes, it would validate Keynes' skepticism about the market *always* returning the best possible results.
There are other paradoxes in Lewis' thinking: Given the amount of government participation in today's economies, removing that participation can only be done through... massive government intervention. Or how about, if it's really Keynes that was the problem, why is so much of the data Lewis raises to refute him post-Keynes in time? Wouldn't it have been easier to just use pre-Keynes data? If Lewis believes in markets so strongly, why is his own firm, Cambridge Associates, privately held?
Nassim Nicholas Taleb, in his book "Fooled by Randomness," asks of stock traders, "Are you good, or are you lucky? How do you know?" We have no idea how successful or not Mr. Lewis has been, because he won't release that data. But if this book is representative of his rigor, there can be little doubt -- He's been lucky.
