> For most people, pro players are replaceable.

I'd argue that professional sport is the closest thing to a true meritocracy - doesn't matter who your Dad knows - you ability is there for all to see on the pitch.

And at the team level - if cosy cliques form, again - team performance doesn't lie - hard work, team work and talent is ultimately what delivers results on the pitch.

The other interesting part of professional sport is that the 'workers' have managed to capture more of the value than is traditionally the case - this is precisely because they are so hard to replace.

If you think professional footballers earn too much and are interchangable - feel free to try and get in the team.
