Whilst you're partially right, you're partially wrong. If you compare your wages to the rest of the world you'd be rich as most people in the world are in poverty. With that being said it's irrelevant.
Maguire isn't doing anything wrong by taking a payout from the club, everyone would do it unless they're a moron. The idea of being a footballer is to play football, but it's not a fairytale, people play for money too. That compensation is for the hard work you put in day in and day out and the sacrifices you have to make. Maguire can't live a normal life due to being a footballer, playing in front of thousands of entitled weirdos (many of whom give him abuse) is not a prize.
