I was not talking about what it is like AT PRESENT, I was talking about what is your opinion on the matter. If you agree with ITF/ATP that roughly 200 athletes should be able to make a living, then your statement is fair, of course. If you think, I don't know, 2000 athletes should be able to do so, then it's not fair. I was only pointing that the "fairness" of your claim depends on personal opinions.
yes, indeed it's my personal opinion. I believe that the number of pros making a living of the sport is fairly around the 300 mark (maximum).
The system is developed this way in order to secure a constant flow of upcoming talents, by giving serious amounts to the TAs, which distribute them to the top youngsters, which is again - money from tennis, for the future of tennis.
If these amounts would stop being distributed to TAs and it goes directly into prize money of lower level tournaments (and having more of them), we'd have players at average and bad level making a living and being in the way of the promising young talents, which latter would get demotivated early on.
On the other side it's fairly hard to find sponsors when you haven't achieved anything (99.9% of the coming juniors), so they would have to start with money from the parents only, which makes it impossible to have a wide base of the pyramid in order to elect the few good ones, who'll climb up.
So older players (above 22 - 23yo) should either make their own money already, or if they feel they have it to become late bloomers - convince sponsors.
That's a fair distribution system, which secures high pays to the top players (top 100) and secures a constant flow of young talents.
