Of course they are, but, typically, they do things to get that money, and end up, going in and out of jail as a result. I am very familiar with this as I saw my own nephew follow this route, until he OD.
Celebrities/Ball Players with money, rarely end up in jail. They end up in the news, going to rehab or on tmz because they overdosed.
You might want to watch, the A&E show, 60 Days in Nacroland, and its goes behind the scenes and tries to show the problems.
