It doesn't really concern them. They aren't traders. They don't trade. After all, capitalism has won the war of guiding philosophical principals. It alone has emerged from the twentieth century virtually unscathed, while communism, fascism, and democracy have all withered.
Capitalism is the only religion in the west that is practiced without an iota of hypocrisy.
Catholics will give lip service to the poor while doting on their bejeweled pope in his glittering palace. Jews will cry out against their own oppression throughout biblical history and up to the present day, and then turn around and oppress or contribute to the oppression of others. Christians, Muslims, Hindus, Buddhists, all will espouse ideals they cannot possibly put into practice in their daily lives. And the more lofty, generous, ascetic, compassionate, transcendental, optimistic, humble, or loving those ideals are, the more impossible will it be to avoid compromising them in the daily business of staying alive, let alone happy, healthy or free. But the capitalist never compromises.
