It's a fair point BSM, but we can't celebrate the life of every good person who passes, we'd all be doing it all the time. So for the majority the people whose lives you have touched and made better will be the ones who mourn your passing.
It just wouldn't work would it, as great as they may have been you wouldn't buy a paper or watch a programme about the greatest teacher in Dundee who enriched the lives of thousands of children who passed through his classes. Not unless there was a special interest.
Famous people may or may not have done anything this great, but they do touch the lives of many in some way so they are of interest and they sell papers/TV programmes. Where you draw your own personal line and take an interest or not is up to you. Jade Goody, couldn't care less, MJ interesting and I like some of his music but I'm not too fussed, Steve Irwin the crocodile man, thought that was sad and an unnecessary loss though he was taking the risk, when Steve Clark from Def Leppard snuffed it I was genuinely shocked and saddened
