Why Productivity, Not Redistribution, Builds Real Wealth

Thomas Sowell has spent decades pressing an argument that most of economics has moved past. Inequality is a fact to be explained, not a puzzle to be solved. The question that deserves attention, he writes, is why some people and some nations produce more than others. Distribution is secondary. Productivity, not redistribution, is what lifts everyone's material conditions and builds real wealth over time.

The framing carries market consequences. The way policymakers read the wealth gap shows up in the tax code and the cost of capital. Regulation follows the same logic. The dominant reading in Washington and in academic economics treats the racial wealth gap as evidence of discrimination and builds policy on that inference. Sowell's work is a sustained objection to it: the gap is real, the cause does not follow from the disparity.

In Disparities and Discrimination, Sowell gathers the empirical studies showing how many variables shape economic outcomes: education, family background, resources, discrimination, criminal records. None of them, in his reading, supports a one-factor explanation. "Neither logic nor empirical evidence provides a compelling reason for expecting either equal or random outcomes," he writes. The warning extends to the assumption underneath much of the wealth-gap literature, which presumes that absent discrimination, outcomes would be roughly equal. The presumption does the causal work, and it is never tested.

The deeper problem is methodological. Economists who study the wealth gap talk as though they are doing causal inquiry. Mises argued they are doing something else. Human action cannot be understood without causality, he wrote in Human Action, and causality in human affairs cannot be separated from purpose. Aristotle identified four causes: material, formal, efficient, and final. The final cause is the purpose a thing serves. Modern economics mostly ignores it.

The natural sciences, Mises wrote in The Ultimate Foundation of Economic Science, are causality research. The sciences of human action are teleological. A ball rolls down a hill because of gravity, and no further explanation is needed. As teenagers like to say, it's not that deep. A person acts the way he does because of the ends he is trying to reach. The two inquiries are different in kind. Conflating them produces economics that mistakes a correlation for a mechanism.

Mises went further. Teleology, he wrote in Human Action, can be called a variety of causal inquiry. Final causes are first of all causes. The category of means and ends presupposes the category of cause and effect. Purpose is not an alternative to causality. In human affairs, it is the form causality takes. The panmechanistic worldview, which admits only mechanical causality, is blind to purpose.
