When Menzi Mngoma decided to get a job as an Uber driver, it was mostly out of necessity. The 27-year-old has a fiancé, kids and his parents to support, and his life's passion, opera, wasn't paying the bills. But he was also making a bet. "You need to be well-connected to go overseas," he told NPR. Though he's currently based in Durban, South Africa, Mngoma dreams of becoming an international musical sensation; he thought that driving Uber might help him make connections with people who could further his career.
