She defines capitalism as "a social system based on the recognition of individual rights, including property rights, in which all property is privately owned." She explains that a defense of private property and laissez-faire capitalism is the only way to defeat racism:

"There is only one antidote to racism: the philosophy of individualism and its politico-economic corollary, laissez-faire capitalism. ... It is capitalism that gave mankind its first steps toward freedom and a rational way of life. It is capitalism that broke through national and racial barriers, by means of free trade. It is capitalism that abolished serfdom and slavery in all the civilized countries of the world."

Walter Williams adopts a similar view of the role of capitalism in defeating racism. He argues that only in a capitalist system, where economic gains are made through free market exchange and not by seeking political preferences and protections, can minorities make economic progress: "Free-market resource allocation, as opposed to allocation on political grounds, is in the interests of minorities and/or less preferred individuals. ... The market encompasses a sort of parity nonexistent in the political arena, where one person's dollar has the same power as anyone else's."

Williams' point is that a racist seller of course wishes to sell his produce; therefore, he will not reject black buyers as he values their dollars as much as the dollars of white buyers. Most sellers would not consider it worth losing the sale simply to be true to their racist beliefs. Even in the case of a racist seller who is willing to pay a price for his desire not to transact with other races, a point is likely to come where his costs mount to a degree that he no longer considers it worthwhile to continue rejecting sales purely on racist grounds. This explains why even in the segregated states, many whites entered into commercial transactions with blacks. Williams writes:

"The fact that some blacks were able to earn a comfortable living and indeed become prosperous — in both the antebellum South, in the face of slavery and grossly discriminatory laws, and in the North, where there was at best only weak enforcement of civil rights — gives strong testament to the power of the market as a friend to blacks."
