Why was a brilliant surgeon and biotech billionaire sued by his brother... and Cher? BBC business editor Simon Jack and journalist Zing Tsjeng trace his journey from apartheid South Africa to the upper echelons of LA society. He’s tried to cure cancer, diabetes, and COVID-19, and along the way rubbed shoulders with some of the most powerful people on the planet: Joe Biden, the Pope, and Donald Trump. He's made his fortune selling drugs to sick people, but his results have been described as "controversial", "hype" and even “old wine in a new bottle”. 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, Simon and Zing judge a man who made cold hard cash from controversial cures.
