This is often the case, but often these people do have good breeding so their raw potential is the same as their parents'.
The problem, most often, is that they've become lazy, and lacked the drive that the people who created the wealth had. Still, they're reasonably intelligent people with a modicum of self respect, so they become a bit embarassed of their wealth, and overcompensate to the outside world by pretending to not be influenced by it.
