Why when a person gets rich and have success the right way there's always a penalty for it?

I watched this episode on Fresh Prince Of Bel-Air about Will and his cousin Carlton being in this franternity group. When the franternity leader saw carlton as a "soft" person because of the life he lives as a rich person that has not experianced the struggle-to-success the rest of the group members had including Will despite the fact that Carlton is a Top-A student and a hard worker when it comes to school work. In the mid-end of the episode where the group has a party the group leader tells Will that he is accepted in the top fraternity group, but Carlton is not accepted depspite all the hard work that had been put on him a lot more than the other group members. Will, instead of entering the group he leaves along with Carlton and when they get home and tells uncle Phil about what had happened and Phil say's "I've worked hard to give my family a better life and somebody say's there's a penalty for success".
