Sowell slyly tries to educate Obama on the virtues of markets

The people who ran central planning agencies usually had more advanced education than the population at large, and probably higher IQs as well.

The central planners also had far more statistics and other facts at their disposal than the average person had. Moreover, there were usually specialized experts such as economists and statisticians on the staffs of the central planners, and outside consultants were available when needed. Finally, the central planners had the power of government behind them, to enforce the plans they created.

It is hardly surprising that conservatives, such as Prime Minister Margaret Thatcher in Britain and President Ronald Reagan in the United States, opposed this approach. What is remarkable is that, after a few decades of experience with central planning in some countries, or a few generations in others, even communists and socialists began to repudiate this approach.

As they replaced central planning with more reliance on markets, their countries' economic growth rate almost invariably increased, often dramatically. In the largest and most recent examples-- China and India-- people by the millions have risen above these countries' official poverty rates, after they freed their economies from many of their suffocating government controls.

China, where famines have repeatedly ravaged the country, now has a problem of obesity-- not a good thing in itself, but a big improvement over famines.

This has implications far beyond economics. Think about it: How was it even possible that transferring decisions from elites with more education, intellect, data and power to ordinary people could lead consistently to demonstrably better results?

One implication is that no one is smart enough to carry out social engineering, whether in the economy or in other areas where the results may not always be so easily quantifiable. We learn, not from our initial brilliance, but from trial and error adjustments to events as they unfold.
