Seriously, Fed and Nadal both came from families who were at least comfortably well off.
As is the case with 95% of all players I suppose. It still is a sport for the relatively 'well-to-do' part of society.
I agree with most here, it's rather unfair to put any blame on a fellow just because he was so lucky to be born in a 'rich' family. In the end, all that will count are his results, as is the case with any player.
I don't understand why some commentators make such a fuss about it. A personal grudge or something?
