People who have everything and could have it so good, could appreciate it and be nice and grateful for their good life, but no, they still have to beat up on the nice guy and the little guy for some demented reason. They don't know how to be nice, or loving and need scapegoats to make themselves feel better. Cruelty just seems to do it for some people. They don't want to change.
All I can say is go where you are treated well and where you are appreciated for the lovely, kind and interesting, person you are. Anytime you feel used, or disrespected by anyone, have the self-esteem/self/love to leave.
