You did not read the paragraph from which that quote was excised, then. There is an obvious difference between betting on yourself and others privately and being sponsored by an online casino. Many european top players, do not gamble much on pool matches. The point I was trying to make was one about recruitment. It is easier to bring kids into a poolhall with a "sport" atmosphere as opposed to a gambling atmosphere. It also becomes easier for a parent to send a youngster to a poolhall without having to worry about them mixing with drug dealers, hustlers etc. The difference between Europe and the US in that regard is not black and white and is somewhat area dependent, but there is a difference. I've only been in the US a few times, but it seems to me that the few poolhalls I visited were not places I would send my kids to.
Also, regarding your points on sponsorship: Most companies do not only sponsor people out of the goodness of their hearts, allthough that is a part of it. They look at what they can get out of it as well, in the form of exposure, preferably the positive kind. With no functioning tour, and no tv-exposure most companies probably feel that they should sponsor other athletes. There is a lot of prejudice towards pool as a game for no good, cheating, gambling bums, and it is partly deserved, that's the sad part. There are lots of deserving young athletes in other sports that do not get sponsored, but behave themselves with perfect decorum and perform well in sports where they may actually be seen by the general public. From a corporate point of view, who would you rather support: A young track runner or a 40+ year old pool player with a somewhat shady reputation? Pools sponsorship has traditionally come from "unhealthy" sponsors like cigarettes and alcohol. Now the only sponsors are usually casinos and the like. Do you ever ask yourself why that is? Pool has gotten so many black eyes that it resembles a pro boxer the day after the fight. Remember Earls sponsorship by Cuetec and how it ended? That kind of thing does not get forgotten easily. These are some of the many reasons why it's an uphill battle to get sponsors for pool players.
If you are really good at something and nobody wants to sponsor you, it's time to re- evaluate your strategy. Ask not what the sponsor can do for you, but what you can do for your sponsor.
