His got properties worth millions of dollars all generating in large revenues owned by an organization he co-founded to collect those income he's generating that allowed him to pay himself to accommodate rich lifestyle. The fact on his Wikipedia page says his got negative networth is a fucking lie because his business are all private and they're legally allowed to keep private transaction private the same goes to private properties from the public unless it's being traded in a publicly traded market or the government is involved usually the IRS.

Come on guys! Think like a rich person would do if they want to hide their wealth to accommodate such amount of money to prevent government from snooping around.
