Are you rich if you earn £70,000 AND should you pay more tax? @armstrong_irwin and @EJWoolf debate

Are you rich if you earn £70,000 AND should you pay more tax? Well according to Shadow chancellor John McDonnell you are. He set out his vision for a "fair taxation system" in an interview on Radio 4 where he said that those earning above £70,000 should pay more in tax. He said "we want to get a system that is fair, so the corporations and the rich pay their way more." Should you pay more at £70,000 and if you are earning that are you rich? Commentator Emma Woolf and businessman Irwin Armstrong debate.
