In today's fast-paced society, the concepts of self-interest and greed have become more prominent than ever. While some people believe that these traits are natural parts of human nature, others argue that they can lead to serious social problems. In my opinion, although self-interest is not entirely bad, excessive greed can bring negative consequences to individuals and society as a whole.

First of all, it is true that everyone has their own interests. People work hard to earn money, improve their living conditions, and achieve personal goals. This kind of self-interest is a driving force for progress. Without it, there would be no motivation for people to strive for success. However, when this self-interest turns into greed, things can go wrong.

Greed refers to an insatiable desire for more, often at the expense of others. For example, some business people may try to make huge profits by cheating customers or exploiting workers. Such behavior not only violates ethical standards but also harms the public interest. In the long run, this will damage the trust between people and even lead to social instability.

Moreover, greed can affect an individual's mental health. People who are always chasing wealth and power may feel stressed and lonely. They might lose sight of what truly matters in life, such as family, friendship, and personal happiness. In contrast, those who live modestly and help others often find greater satisfaction and peace of mind.

In conclusion, while self-interest is a normal part of life, we should be cautious about greed. It is important to strike a balance between personal goals and the well-being of others. Only by doing so can we build a fairer and more harmonious society.
