Brazilian tycoon Carlos Wizard Martins has never set foot in Venezuela, but the Mormon businessman is on a mission from God to help thousands of desperate migrants crossing the border to restart their lives. At 62 and nearing retirement from businesses including Taco Bell and Mundo Verde that have turned him into a self-described billionaire, Martins is living on the Brazil-Venezuela border where he runs a volunteer network assisting migrants settle in other parts of Brazil.
