I think that's rubbish. A lot of people will, obviously. But there is absolutely no reason why we should think of this as natural or inevitable. Firstly, most players clearly do not act on the basis of single-mindedly maximising their earnings. If that was the case, the chinese league would have been full of prime talent years ago, and Ronaldo and Messi would already be playing in Saudi Arabia. Ronaldo will make about 7 times what he did at United, which was already an absurdly high wage, but he would have taken much less to play for a top club in Eurpoe, if anyone would have had him. Clearly, top football players generally do not simply act to maximise their earnings, with no other considerations impinging.
Then there's people like Eric Cantona, who'd rather have self-respect than even more money. Seems perfectly sensible to me.
