More and more it appears behavior especially among the younger generations has less to do with wealth than it does with "discretion".
Children of "privilege" become drug addicts, are sexually promiscuous, have unplanned pregnancies, and commit crimes too.
The major difference is their families have teams of lawyers and influence to either "make it go away" or keep it from becoming public in the first place. Also white collar crime is still a crime.
You look at Paris Hilton who comes from a very prominent wealthy family, numerous Kennedys have sat in front of a judge and it's not uncommon to see very wealthy celebrities and athletes or their children in trouble with the law or not displaying (class) in public.
Various monarchies have been known to had instances of incest.
As the old adage goes:
"No one knows what goes on behind (closed) doors."
Even with the photo you have of Vanessa Williams. I consider her to be very cultured and a class act. Nevertheless there are many who recall the nude photos in Penthouse Magazine and would hold that against her for life. For many what you do is who you are.
