Rational self-interest is the objective ethical code.
Each man should seek his own happiness through a productive life in which his own independent, rational judgement is his only guide to action. No man should sacrifice himself to others nor others to himself. The primary virtues of the Objectivist ethics are rationality, independence, integrity, honesty, justice, productiveness, trade, and pride.
Objectivism rejects altruism, the doctrine that the highest good is service to others---whether "others'' denotes a state, a deity, one's family, "society,'' or the poor and disadvantaged.
