How did being fired from Wall Street lead Michael Bloomberg to a $96 billion fortune and a failed presidential campaign? Journalist Zing Tsjeng and BBC business editor Simon Jack try to understand this man of contradictions. A brash playboy and thoughtful data nerd, a lifelong Democrat who became the Republican mayor of New York, a plutocrat who spent $1 billion self-funding a short-lived presidential campaign, and one of the world’s greatest philanthropists.

In the podcast that uncovers how the world's wealthiest people made their money and asks if they are good or bad for the planet, Zing and Simon judge a man whose eponymous Bloomberg terminal sits on desks throughout the finacial world, and helps make people incredibly rich.
