The Friedman doctrine states that a company's sole responsibility is to maximize profits for its shareholders. It argues that companies have no social responsibility. Milton Friedman was the main proponent of this view. Many companies initially adopted this approach but now also consider corporate social responsibility. Critics argue it neglects a company's responsibilities to society. Alternatively, Carroll's four responsibilities of business identify economic, legal, ethical, and philanthropic responsibilities in order of importance, with economic being the baseline requirement.
