He's an idiot. I really wanted to like Corbyn as a lot of what he believes in I can get behind, but statements like this make him un-electable to most people. Even if you earned no where near this imaginary cap, would you support the idea of others not being able to earn more if they've worked for it?
Companies who HQ themselves in the UK would move abroad so fast if this ever came close to being discussed officially. I understand that he's trying to bridge the inequality gap, but you surely do this by upping the lowest wages rather than limiting the highest. There should be a stronger floor to protect people from not being able to live rather than putting a cap on what people can earn. As manygoose says, so long those earning stupid salaries to start with are paying their taxes and spending their money then who cares?
Who cares whilst the CEO's are earning a fortune the tax payer is picking up the pieces through tax credits, and other benefits to top up the minions wages ?
