This author began with a hypothesis, and then engaged in motivated reasoning in order to confirm it. All we need to do is look at who the best distance runners in the world are: Kenyans, Ethiopians, Moroccans -- these are not people with above-average annual incomes or large net worth. By deliberately excluding the entire continent of Africa from the scope of analysis, the author talks himself into a baseless and silly theory. Endurance sports have always been sports of the people.
