There is some truth to it, but it is not entirely correct. True confidence comes from your control over power, and only then from your economic strength.

Wang Zhiwen's lines are too classic:
"When you have experienced the pressure of the economy, the hardships of marriage, the cruelty of society, and the malice of human nature, you will realize that material wealth is the foundation of existence. Everyone's confidence comes from their economic strength. I didn't believe this before, but now I firmly believe that as long as the interests are in place, strangers are all friends. When interests disappear, friends become strangers. Don't argue with strangers. When working away from home, remember to seek wealth without conflict. As long as it doesn't affect your interests, if he says the sun rises in the west, you agree. Mice never think that what they eat is stolen. Flies never think they are dirty. Bats don't know they are toxic. After all, in the world of crows, swans are all guilty. If the thoughts are not on the same level, there is no need to conquer each other."
