Through a series of experiments, scientists believe that money can stimulate people's exclusivity, which is likely to be a human instinct reaction, just as love has exclusivity. When there is a monetary interest in cooperation, people will instinctively protect themselves. Therefore, they will respond to the other party with an offensive attitude and generate a certain degree of aversion. As a result, there are various phenomena that money destroys love, pollutes affection, and cuts off the friendship, showing that humanity is really hard to beat the copper smell. However, experiments have also confirmed that while people have an exclusive mind in the face of money, their independence and creativity have also been significantly enhanced. Moreover, money, as an important product of human civilization, must always exist, and avoiding it is obviously unrealistic. From this text, you can judge the author's point of view?
