It is apt to say capitalism inherently lacks ethics. And in a world where competition is the main attribute describing society, that lack is what breeds success. Which is why one could even exaggerate and say that capitalism fosters sociopathy. Individuals that grow to lose their sense of ethics are favoured and more likely to succeed in positions of power, while those restricted by their morals are quickly pushed aside. So while we say capitalism can be good or bad, it is more likely that it leans towards the bad.
