Why Central Planning Fails
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. No matter how honorable the central planners' intentions, they will fail because they cannot know the needs and wishes of 300 million different people. And if they somehow did know their needs, they wouldn't know them tomorrow.
