It's kind of important for me to hear your thoughts on this because maybe it would have been worse for him had he lived. And then I might come to the conclusion that it's good the way it is.
Unfortunately, I believe that Michale's life would not have taken a turn for the better, even if it looked like it in 2009. He had immense debts that could only have been settled through the tour and further subsequent tours.
But sooner or later he would certainly not have been able to continue and everything would have collapsed on him. He also had a tendency not to keep contracts and he would certainly have breached the contract with AEG at some point. More debts, more lawsuits and extreme payments to various lawyers (see the bodyguards' book).
He might even have lost custody of his children at some point. I think Michael would have lived a life on the run like he has since 2005. And once he was down, the likes of Wade Robson would probably have crawled out and staged another high profile trial.
I don't think Michael would have gotten much into producing music and films. Maybe 1-2 new songs, maybe a duet with Justin Bieber or Will.I.Am.
But it is also well known that he was not very reliable with his partners in the music industry in the last years of his life.
I believe the downward spiral would have continued and Michael would still be taking painkillers and feeling infinitely sad to this day.
But it's interesting to read what you guys think about it.
