Well I would agree with you about the other two but for Michael Jackson it's not applicable to him cause he died leaving a legacy of assets behind that till date he's known and remembered for his deeds, and at such there's still much left on his behalf but likes of Mozart he was known to be a successful song writer but i think he was misled which results to his bankruptcy. One thing I know is that people will always remain in debt no matter how much they make or get.
People will only be in debt if they aren't grateful for what they already have, leading them to go into debt to fulfill their own desires. Generally speaking, this is true because I often see many people in debt even though they have an income and are able to cover all their debts. But that doesn't mean there aren't grateful people in this world. On the other hand, I still find people who are grateful for their income without being carried away by egos to have something they can't currently achieve.
