While nobody is surprised, still feels like the beginning of the end of an era. I guess the only question is how long Nadal will hang on. My wife and I joke that Djokovic will still be crushing 20 year olds for years to come, but time catches all of us eventually.<p>It feels like it's worth mentioning that almost all pro tennis players declare residency in places like Monte Carlo to avoid taxes. This makes sense since they are on the road 90% of the year anyway so why pay super high taxes back home? Federer, however, retained his residency in Switzerland, paying very high taxes on his $130mm (!!) in winnings (not to mention all the other income from sponsorships, etc). In a world where wealthy people hyper-optimize to avoid paying their fair share, playing the "it's all perfectly legal!" card, it is comforting to occasionally see someone who says, hey, I have plenty, maybe I'll pay it forward a bit so the next generation can have the same opportunities I had.
