When did entering a rehab facility become the mea culpa for all wrongdoing in Hollywood?

Every day someone is entering rehab or a "facility" to "heal". I agree that the likes of Mel and Isaiah need some guidance, but aren't they really just entering a program to appease the social groups who are raising the errors to a higher level in the media? Do you really think a 6-week stint in a facility ends a lifetime of racial or homophobic slurs and beliefs?

And what about all the stars who go into rehab because they party too much? Partying has always been a phase in young people's lives....not all young people.....and not to the degree the stars do it, but nonetheless, most college-going, social people have a phase at least. Does that mean they have a problem? Not necessarily, maybe some of them yes. I was relieved when Danny Devito just admitted he was drunk on The View and moved on.....I was waiting for the rehab announcement, but it never came.

Let's face it, they are probably ONLY doing these things to salvage a career....and the millions they face to lose. What do you think? Do you think they really want to "heal"?
