One of the great errors of big government liberalism is its belief that inhuman systems are superior to human beings. This form of mechanical thinking is a commonplace error in a scientific age in which we have become used to using mechanical systems to solve problems. But people are not machines, and trying to turn people into gears in the great machine of government leads to tragic results.
The embrace of big government in the United States was driven by the belief in scientific government as a perfectible system. This creepy worship of elitist technocracy lingers around the more idealistic liberal administrations, from FDR to JFK to Obama.
