I don't think he is. See, he's lived his entire life in a world without consequences, and he's never actually been a good businessman, and certainly never invented anything. But he's built his own little brand around pretending he's both and not a con man who was scamming carbon credits to boost the stock price of his flagship company.

At some point, he started to believe his own branding. After all, he must be a good businessman if he's the richest man in the world, right?

As a note, Bernie Madoff had a net worth of almost $70 Billion at his peak. He was one of the richest men in the world.
