The case studies discussed in this assignment highlight various ethical issues faced by corporations, including Wal-Mart's exploitation of low employee wages, shipbreakers' disregard for environmental and worker safety, and Plasma International's profiteering from blood donations. Utilitarianism, a moral theory that prioritizes the greatest good for the greatest number, is applied to these cases to evaluate their ethics. It suggests that corporations should prioritize the well-being of both employees and the environment, rather than solely focusing on profits. While utilitarianism can be an effective tool for evaluating ethical decisions, it also has its drawbacks, such as ignoring individual human experiences and prioritizing social acceptability over moral principles.
