Walter Williams, professor of economics at George Mason University, shows how self interest goes much further than charity:

What human motivation leads to the most wonderful things getting done?

How about the charity and selflessness we’ve seen from people like Mother Teresa? What about the ceaseless and laudable work of organizations like the Red Cross, Habitat for Humanity and Salvation Army? What about the charitable donations of rich Americans, to use the silly phrase, who’ve given something back?

While the actions of these people and their organizations are laudable, results motivated by charity and selflessness pale in comparison to other motives behind getting good things done. Let’s look at it.

In December 1999, Stephen Moore and Julian L. Simon wrote an article titled “The Greatest Century That Ever Was,” published by the Washington, D.C.-based Cato Institute. In it they report: Over the course of the 20th century, life expectancy increased by 30 years; annual deaths from major killer diseases such as tuberculosis, polio, typhoid, whooping cough and pneumonia fell from 700 to fewer than 50 per 100,000 of the population; agricultural workers fell from 41 to 2.5 percent of the workforce; household auto ownership rose from one to 91 percent; household electrification rose from 8 to 99 percent; controlling for inflation, household assets rose from $6 trillion to $41 trillion between 1945 and 1998. These are but a few of the wonderful things that have occurred during the 20th century.

Returning to my initial question: What human motivation accounts for the accomplishment of these and many other wonderful things? The answer should be obvious. It was not accomplished by people’s concern for others but by people’s concern for themselves. In other words, it’s people seeking more for themselves that has produced a better life for all Americans.
