Walter Williams‘ latest column explains why the president’s efforts to engage in class warfare are — to put it mildly — counterproductive.

President Obama, in stoking up class warfare, said, “I do think at a certain point you’ve made enough money.” This is lunacy. Andrew Carnegie’s steel empire produced the raw materials that built the physical infrastructure of the United States.

Bill Gates co-founded Microsoft and produced software products that aided the computer revolution. But Carnegie had amassed quite a fortune long before he built Carnegie Steel Co., and Gates had quite a fortune by 1990.

Had they the mind of our president, we would have lost much of their contributions, because they had already “made enough money.”

Class warfare thrives on ignorance about the sources of income. Listening to some of the talk about income differences, one would think that there’s a pile of money meant to be shared equally among Americans.

Rich people got to the pile first and greedily took an unfair share. Justice requires that they “give back.” Or, some people talk about unequal income distribution as if there were a dealer of dollars.

The reason some people have millions or billions of dollars while others have very few is the dollar dealer is a racist, sexist, a multi-nationalist or just plain mean. Economic justice requires a re-dealing of the dollars, income redistribution or spreading the wealth, where the ill-gotten gains of the few are returned to their rightful owners.

In a free society, for the most part, people with high incomes have demonstrated extraordinary ability to produce valuable services for — and therefore please — their fellow man.
