… Differences in capabilities are inescapable, and they make a big difference in what and how much we can contribute to each other’s economic and other well-being. If we all had the same capabilities and the same limitations, one individual’s limitations would be the same as the limitations of the entire human species.
We are lucky that we are so different, so that the capabilities of many other people can cover our limitations.
One of the problems with so many discussions of income and wealth is that the intelligentsia are so obsessed with the money that people receive that they give little or no attention to what causes money to be paid to them, in the first place.
The money itself is not wealth. Otherwise the government could make us all rich just by printing more of it. From the standpoint of a society as a whole, money is just an artificial device to give us incentives to produce real things — goods and services.
Those goods and services are the real “wealth of nations,” as Adam Smith titled his treatise on economics in the 18th century.
Yet when the intelligentsia discuss such things as the historic fortunes of people like John D. Rockefeller, they usually pay little — if any — attention to what it was that caused so many millions of people to voluntarily turn their individually modest sums of money over to Rockefeller, adding up to his vast fortune.
What Rockefeller did first to earn their money was find ways to bring down the cost of producing and distributing kerosene to a fraction of what it had been before his innovations. This profoundly changed the lives of millions of working people.
