One: If you have more money than you demand.
Two: He has a talent that no one else has.
If there is more money, people think of themselves as the king of the world. They forget who, when, what. And if you have talent, you consider yourself the number one talent in the world. You forget the small and big differences, you don't care about people. If anything is more than necessary, arrogance goes into people. Then people become human and become inhuman.
Not everyone is the same again, but in most cases it is.
