Are footballers included?

Jeremy Corbyn believes that a national maximum wage should be introduced to cap the salaries of high earners.  

I look forward to footballers being top of his list for those he is targeting.  Surely it is obscene in any society for a person to be paid £142,014 a week for kicking a ball.  That tots up to £7,284,000 per annum.  Yip, £7,284,000 per annum.  That is the average wage of a premiership footballer in one of the top 5 clubs.

A nurse in the UK earns on average  £23,091 per annum.  So a footballer "earns" 315 times more a year than what a nurse does. 

That really cannot be right in anyone's book.
