people are people, rich or poor. being an a$$hole or jerk, or good person isn’t dependent on how much you make. Being rich can help a jerk be a bigger jerk, and being really poor can help a jerk be really more violent and a thug.
But money or lack of money doesn’t force a personality change that isn’t inherent within the person. It may help accelerate it, but it isn’t the source of that person’s “a$$holeness”. That resides in a person’s heart.
