The criterion of truth is that it works even if nobody is prepared to acknowledge it. - Ludwig von Mises

People do not cooperate under the division of labor because they love or should love one another. They cooperate because this best serves their own interests. Neither love nor charity nor any other sympathetic sentiments but rightly understood selfishness is what originally impelled man to adjust himself to the requirements of society, to respect the rights and freedoms of his fellow men and to substitute peaceful collaboration for enmity and conflict.

People must learn that the accumulation of wealth by the successful
conduct of business is the corollary of the improvement of their own standard of
living and vice versa. They must realize that bigness in business is not an evil, but both the cause and effect of the fact that they themselves enjoy all those amenities
whose enjoyment is called the “American way of life.

"Nothing is more unpopular today than the free market economy, i.e., capitalism. Everything that is considered unsatisfactory in present-day conditions is charged to capitalism. The atheists make capitalism responsible for the survival of Christianity. But the papal encyclicals blame capitalism for the spread of irreligion and the sins of our contemporaries, and the Protestant churches and sects are no less vigorous in their indictment of capitalist greed. Friends of peace consider our wars as an offshoot of capitalist imperialism. But the adamant nationalist warmongers of Germany and Italy indicted capitalism for its "bourgeois" pacifism, contrary to human nature and to the inescapable laws of history. Sermonizers accuse capitalism of disrupting the family and fostering licentiousness. But the "progressives" blame capitalism for the preservation of allegedly outdated rules of sexual restraint. Almost all men agree that poverty is an outcome of capitalism. On the other hand many deplore the fact that capitalism, in catering lavishly to the wishes of people intent upon getting more amenities and a better living, promotes a crass materialism. These contradictory accusations of capitalism cancel one another. But the fact remains that there are few people left who would not condemn capitalism altogether."
