Mercenary behavior may get short-term economic benefits, but it is not good for long-term development. In addition, mercenary behavior often causes losses to others, which leads to social dissatisfaction and illegal behavior. This kind of behavior is considered as a bad psychology and one of the important reasons leading to social problems.
In order to avoid mercenary behavior, we should cultivate good values and moral concepts. We need to rationally realize that everyone has a responsibility to society, and this sense of responsibility also needs to consider the interests of others, not just personal interests. Therefore, we need to constantly improve ourselves and care about social development and the interests of others.
