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.

John Stossel ObamaCare reflects the "bone-headed audicity" of central planners

The 1,990-page bill is breathtaking in its bone-headed audacity. The notion that a small group of politicians can know enough to design something so complex and so personal is astounding. That they were advised by "experts" means nothing since no one is expert enough to do that. There are too many tradeoffs faced by unique individuals with infinitely varying needs.

Government cannot do simple things efficiently. The bureaucrats struggle to count votes correctly. They give subsidized loans to "homeowners" who turn out to be 4-year-olds. Yet congressmen want government to manage our medicine and insurance.

Competition is a "discovery procedure," Nobel-prize-winning economist F. A. Hayek taught. Through the competitive market process, we producers and consumers constantly learn things that force us to adjust our behavior if we are to succeed. Central planners fail for two reasons:

First, knowledge about supply, demand, individual preferences and resource availability is scattered -- much of it never articulated -- throughout society. It is not concentrated in a database where a group of planners can access it.

Second, this "data" is dynamic: It changes without notice.
