I respect your opinion, and a fair few will share it, but I personally disagree. Players may as well get second jobs from the end of January to the start of June, and from now until January if that was the case. Indian Wells aren't going to put up $9m each for both men and women's tournaments every year, and almost $1.5m for the respective winners if it's effectively a nothing event. Shenzhen have put up the biggest purse in tennis history to secure the WTA finals, the winner will get more for winning that than any slam - these events do matter.
A Canadian winning the Rogers Cup will be (and is) massive in that country, and I'm sure Andreescu will have inspired many a Canadian with her recent success, likewise I'm sure kids in Germany will have watched Zverev's O2 success last year and the fact that he became the 3rd best player in the world at one time and would think, hey, he's pretty good at what he does.
Obviously slams are the focal point of the season and where the vast majority of interest and spotlight lie, but IMO there's plenty of tennis outside of them to be able to build reputations.
Based on your posts you know far more about tennis than I ever will but I never meant money wise , I meant in the grand scheme of things , slams are what you are judged on. Everyone knows how many slams Federer, Nadal and Djokovic have won, nobody cares less what they have won after that, just like nobody really cares what these so called next superstars have won unless it is a slam.
