As history has also shown, especially in the twentieth century, one of the first things an ideologue will do after achieving absolute power is kill. - Thomas Sowell

Any serious consideration of the world as it is around us today must tell us that maintaining common decency, much less peace and harmony, among living contemporaries is a major challenge, both among nations and within nations. To admit that we can do nothing about what happened among the dead is not to give up the struggle for a better world, but to concentrate our efforts where they have at least some hope of making things better for the living.

A society that puts equality — in the sense of equality of outcome — ahead of freedom will end up with neither equality nor freedom. The use of force to achieve equality will destroy freedom, and the force, introduced for good purposes, will end up in the hands of people who use it to promote their own interests.

External explanations of black-white differences — discrimination or poverty, for example — seem to many to be more amenable to public policy than internal explanations such as culture. Those with this point of view tend to resist cultural explanations but there is yet another reason why some resist understanding the counterproductive effects of an anachronistic culture: Alternative explanations of economic and social lags provide a more satisfying ability to blame all such lags on the sins of others, such as racism or discrimination. Equally important, such external explanations require no painful internal changes in the black population but leave all changes to whites, who are seen as needing to be harangued, threatened, or otherwise forced to change.
In short, prevailing explanations provide an alibi for those who lag — and an alibi is for many an enormously valuable asset that they are unlikely to give up easily.
