Do you dislike others who are "better off" than you are?
If your parents couldn’t help you through college, do you dislike the kids whose parents paid their way, maybe along with a nice car?
If you aren’t normally found as physically attractive, do you dislike those who are?
If you didn’t land quite as impressive of a job as the peer who graduated with the same degree as you did, do you hold that against them?
These are just some of the first examples that came to mind, but the situation could be applied to any aspect of life. Do you find yourself being put off by people simply because they are doing better in some aspect of life than you are? Does it depend whether or not they brag about it? Do you take into consideration that maybe they worked/earned their way to where they are? Or, if they came from a wealthy family, the fact that they can’t control what their parents are any more than you could control what your parents are? Do you stereotype these people and if so, how?
