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.
