The media and academia are continuously obsessed with "gaps" and "disparities" in income. As one talk show host put it, "It makes no sense" that a corporate executive makes over $50 million a year.

Complex economic processes cause all these things to be done and coordinated by a wide variety of people, just in order to produce something as simple as a lead pencil. Multiply that by a hundred or a thousand when it comes to the complexity of producing a car or a computer.

If you cannot understand something as simple as making a lead pencil, why should you be surprised that you don't understand why someone is making a lot more money than somebody else?

Moreover, if this obsession with income disparities is to be something more than mere hand-wringing or gnashing of teeth, obviously the point is that somebody ought to "do something" to change what you don't understand.

Of course, such political control of incomes is usually advocated only to deal with "the rich." But, when income taxes were imposed in the early 20th century, they applied only to "the rich" and they took a very small percentage of their income.

Once the floodgates are opened to this kind of political power, however, we have seen with the income taxes that they not only spread far beyond "the rich," they took a serious share of even middle class incomes. Continued...
