Via Walter E. Williams:
The fact that we have gross ignorance about how the world operates is ignored by the know-it-all elites who seek to control our lives. Let’s look at a few examples of the world’s complexity.
According to some estimates, there are roughly 100 million traffic signals in the U.S. How many of us would like the U.S. Congress, in the name of public health and safety, to be in charge of their actual operation? Congress or a committee it authorizes would determine the length of time traffic lights stay red, yellow and green and what hours of the day and at what intersections lights flash red or yellow. One can only imagine the mess Congress would create in the 40,000 cities, towns and other incorporated places in the U.S. But managing traffic lights and getting good results is a far less complex task than managing the nation’s health care system and getting good results, which Congress tries to do.
The bottom line is that each of us is grossly ignorant about the world in which we live. Nothing’s wrong with that ignorance, but we are stupid if we believe that a politician can produce a better life than that which is obtained through peaceable, voluntary exchange with our fellow man anywhere on earth.
