In the NFL, all top 1000 players are making close to $1 million a year. That is top 1000. Not to mention it is garuanteed contract money over multiple years. and $100's of thousands in signing bonus's. Now, there is A LOT more money in the NFL, but if you looked at the proportional funding the funding supports more players to make a good lviing and compete. Tennis could certainly do better, and giving lower ranked players more to live on for competing would allow, well...more opportunities for them to advance.Problem with that is you would hurt the sport long term. If only the top 20 or so are making good money, there will be less players able to support themselves and build up their skills, as they will not have much time to do so. Imagine a player trying to make it on tour for 3 to 4 years outside the top 50 or even top 100? If they dont bring home $300,000 + a year, then it will be hard to keep doing it. You would most likely have a fallout in level except for the very top players. In this case, you might have to reduce draws to have a more competitive tour.
Just looked it up. The 75th ranked player made $630,000 a year, however, if you reduce this to under $400,000 by decreasing early rounds and giving more money to the top end players, these players will have less resources, and possibly even less drive. While this is a great salary, it would rank about the worst of any major sport in the world for average top 100 players. Most of the major sports have minimum of like $600,000... minimum, and those guys are like outside the top 300 top players.

The fight there has always been the disparrity of tournament income vs. payout. Hard to draw direct line comparisons of team v individual sports, but worth noting.
