I think not only should moderation be applied to individuals, but also to corporations. Maximizing economic profit is the most important object to companies. However, a company cannot neglect the interest of other related groups and social benefits. So during the process of operating business, the enterprise should have self- regulation in the face of economic profit. For example, as an automobile producer, it should deal with the relationship between the interest and environment. The company can develop technologies to reduce the level of air pollution.
