Unfortunately Ed, it's only once someone actually commits suicide that people actually care about mental illness. While I think you have something of a point (suicide is a rather selfish way out), you have to realise that mental illness is hugely stigmatised everywhere still.
While he had all the opportunities to get it sorted out unlike us plebians may not have, what if he actually did? People he knew and loved would most likely tell him he's being selfish, he has everything how can he be unhappy, he just needs to pick himself up, etc. etc. etc. No matter if you're rich or poor, these social judgements are everywhere and they are truly what make mental illness difficult to get out of -- people are not supportive, they are judgmental. If the media picked up on the fact that he was depressed or suicidal, it'd probably be a megaphone about how the lead singer of Linkin Park (I think? I don't know this guy) was being an entitled little git who thinks he can be unhappy with all he's got (or something, making this shit up, highly doubt it would be positive or supportive though, it only ever is after the fact).
So the problem is not that this guy was selfish I would say, rather we still have a long way to go regarding mental illness and it's causing even the rich and the wealthy to take their lives even though they have every opportunity to sort that shit out.
Poor guy though, no idea who he is but it's always sad when anyone dies. :(
