Pool is like the drug addicted friend who's burned everyone he knows 3 times too many. People got on with their lives and pretend he doesn't exist. At some point you have to cut your losses, which is what every potential sponsor is doing. Pool is boring to watch. It could be made into passable entertainment with great commentary, with professional commentators who are well prepared, build up narratives and rivalries etc...Alas, we'll never get the chance again. We wasted the best opportunities we had. If you think "Well, that's just in the US", you're sadly mistaken. The same misguided worship of hustlers and con-men exist in Europe as well. We had a mini-Don Mackey situation in the country where I live, in my former club in fact. Some fast talker ran off with sponsorship money and the clubs funds. I tried to warn people, but nobody would listen. That was a decade ago, but then a couple of years ago, a much bigger situation arose with an international player tournament and embezzling funds, that luckily was barely prevented from going nuclear. People were getting paid, at great cost to the people whom the con-man duped.
Somehow the entire culture of the game is corrupt to the core. How it happened, I don't know, but I do know that it is persistent and widespread. Also, it's the one problem that can't be solved by throwing money at it.
