Three things seem to come up frequently in these kind of discussions: Olympics, Government Funding and what did WPA do for players? When I watched the podcast where they had the EPBF guy on it was apparent as well, that Europeans and North-Americans live in quite different bubbles/universes. Of course, that's the beauty. Differences are interesting.
Some countries (e.g. most of the Europeans) intentionally support amateur sport and talent development. It's good for their citizens, physically and mentally. So, many societies deemed it valuable to support. (Same with cultural things like music and the arts,...) Most of these countries set up a system, how they support these sports. To get a fair piece of the pie, it has to be a recognized sport by the IOC and organized. That nurtured a whole pyramid organization in each sport. National, Regional foundation and them being organized in the WPA to be IOC-recognized. That's just what these governments go by. You do a valid sport, you organized yourself, you get government support. Funding for top talent to have pro conditions is only a small portion of this. It goes much deeper: Soccer clubs get slots in school gyms in the winter, clubs can get sponsor money and the sponsor gets tax write-offs for sponsoring a sport (doing good for the society). To have these benefits you have to organize and at least try to be olympic. That's also the reason why there are team leagues for sports like Tennis, Chess or Pool. Sounds counter-intuitive for non-team sports, but that's how recognition as a sport works.
Seems like in the US, without a government sponsor system, everything has to be private engagement. Other than that there are only High School or College Programs for most sports. If you ask, what the WPA ever did for players in the US, they are the wrong ones to ask. You would have to ask a national federation to do this. In Germany it's the DBU, who runs the leagues or national/regional championships. As well as regional and national trainng camps and instructor development. It's the EPBF who runs the Eurotour and European Chamiponships. They only need the WPA to standardize rules and represent to the IOC. Plus, ideally, run World Championships. It should not be the WPA's mission, to run a pro tour.
A few friends here in the US, I talked to about the differences of Pool in Germany and the US, initially always thought of Europe being the land of milk and honey. But it's just different and comes with it's own downsides. They are trapped in mega-bureaucracy. 20 years ago, I remember these huge discussions about dress codes in even the most local beginner's leagues. They were soo restrictive for no reason: black pants, no jeans, black dress shoes, Team Dress shirts, ....... And, for course, no drinking. Some places had a secret drink menu with items like "brown Orangina".
Here in the US I wish there would be more on offer for ABC players to play and develop in one nationwide system, instead of all these scattered APA, BCA, etc.
