This paper will show that if we take conventional ethics seriously, then there is no moral justification for business profits. To show this, we explore three conventional ethical theories, namely Christian ethics, Kantian ethics and Utilitarian ethics. Since they essentially reject self-interest, they also reject the essence of business: the profit motive. To illustrate the relationship, we will concretize how the anti-egoist perspective expresses itself in business and business ethics. In business, we look at what many businesses regard as proof of their virtue. In business ethics, we look at what many business ethicists say about the relationship between morality and self-interest and, thus, the profit motive. Ultimately, we will argue that conventional ethics can, at most, only justify the means of business (i.e., aspects of running a business), but not the end of business (i.e., profits).

本文将表明，如果我们认真对待传统道德，那么就没有道德上的商业利益辩护。为了说明这一点，我们探索了三种传统的伦理理论，即基督教伦理，康德伦理和功利主义伦理。由于他们本质上拒绝自我利益，他们也拒绝商业的本质：获利动机。为了说明这种关系，我们将具体化反自我主义者的观点如何在商业和商业道德中表达自己。在业务中，我们着眼于许多企业视为其美德的证明。在商业道德中，我们研究了许多商业道德主义者对道德与自我利益之间的关系以及由此产生的利润动机的看法。最终，我们将论证传统道德最多只能证明业务手段（即经营业务的各个方面）合理，而不能证明业务结束（即利润）合理。
