Michael Jackson is a good example of how being rich and successful can lead to behavior that just feeds into mental sickness. He probably thought being rich and successful justified his aberrant behavior and that he shouldn't put himself on the level of those below him, until he eventually ended choosing drug abuse over therapy. His whole obsession with children can be traced back to his insecurities that he had been deprived of a childhood, probably in no small part due to growing up as as part of the Jackson musical group family. He must have thought he could relive with his childhood through someone else's by using his wealth and power to create Neverland Ranch.
