Football reflects society. We have some with so much money that they don't know what to do with it, some with more money than others which gives them a superiority complex (they believe that if the wind changes they just might get into the super rich club) a few who are content with what they have and know that chasing more money brings misery and the plebs.
You would be surprised how little some players are on. They certainly aren't in it for the money.
