The pursuit of self-interest and the concern for other people’s welfare

Defend or criticize a conception of well-being or an account of what makes life good by making an argument that addresses the topic question(s) and responds to some of the problems and arguments from the texts we’ve considered in the first few weeks of class.
Explain the connection between the pursuit of self-interest and the concern for other people’s welfare. Can a person live a genuinely good life without taking the interests of other people into consideration, especially when those interests may be in conflict? In other words, is it really possible to live well and fare well in life while devoting oneself exclusively to the pursuit of self-interest? Or does a person’s well-being partly depend on caring about the needs and interests of other people?
