Hasn't the sportsworld redefined "wealth possession" for this 21 Century?

I would not limit it to the sports world, and definitely not just European football. Baseball players, basketball players, american football players, etc, make much more than they are worth to run around on a field or court for a few hours a day and entertain some people. But, this is also true of Hollywood/movie and music industries. Entertainment in general is a big business, and most of the people in any of those realms do not have a college degree at all, some not even a high school or equivalent. The new wealth definition in general I would say has come about by changes in culture and what culture decides are important. And obviously western culture today has decided that having fun is more important than eating and having a decent roof to live under. But by nature of economics and probably human nature there will always be a misbalance of wealth in some form or fashion, be it drug lords or business tycoons or sports heros. Maybe awareness and some reality checks can help ease this problem, anyway, starting with questions like yours.
