what social impacts on the public are cause by footballers wages being too high?

[Faz]

In a free market economic sense, the wage can never be too high - it is determined by the forces of demand and supply. The demand for footballers is a derived demand, driven by the price votes from fans and spectators, who buy tickets to watch their heroes in action.

In the long run, this acts as an incentive for kids and others to become footballers, and as the supply of footballers increase (assuming demand remains constant), then naturally the wages of footballers would fall.

There are huge differences in the wage of top class world footballers and mediocre ones. The demand for a particular footballer depends on his prospective performance, as predicted by previous accomplishments and results.
