I don't know :S I honestly know nothing about football, I would only hazard a guess its fear of an un-known commodity.
I guess, don't get me wrong I think the philosphies behind a lot of peoples lifes leave a lot to be desired. At what point does a hobby becomes consipicious consumption. Why are so many people concerned with say lack of free university tutition when so many people are starving.
But in relation to this, it is so incredibly simple, if people don't like the amount of money given to a trader, or a developer or a quant. Get into their industry, that way the supply and demand curve will even out a bit. If they are not able to, then all they are left with is to attack a society in which we are not all equal, the problem is that why should I work a remotely stressful job? If they all renumerated the same odds are I could easily do something a lot less stressful, and I'm not even on a trading desk anymore (that was exhuasting!).
