Here is a list of prize money won to date:
Thomas Johansson (100) has earned $227,690 so far this year. What do you imagine his expenses (travel, coach, trainer, etc.) have to be for a year? How much of this (after taxes) does he retain?
Perhaps ToJo was a bad example (because he is well known and probably makes money on endorsements as well). But what about other players ranked close to him in prize money (say Marcos Daniel at 113)? I can't imagine he makes much (if anything) on endorsements. How does a guy like this make it out there?
Does anyone have insight into the life of a lower ranked / lesser known professional tennis player? Are they independently wealthy? Do they have wealthy relatives? How can they make it?
