The Milkens – $3.7B
Michael Milken will probably be infamously wealthy forever. We used that adjective because he has been implicated in the insider trading scam that rocked Wall Street. He is seen as the junk bonds architect, which are high-yield and poorly rated bonds made by financiers to dupe investors and creditors. It jumpstarted a domino effect during the late ‘80s. Mikken pled guilty to the charges and received a two-year prison sentence. He has since turned to cancer research and survived cancer.
