Thank you for sharing your thoughts.
On (a), it gives the Europeans and Asians a chance to compete with crème de la crème Americans.
For (b), America gives our foreign counterparts a platform to play, making them more visible to domestic and foreign markets. Thorsten just won the Challenge of Champions, as an example. He's German, though lives in America and competes in American pool competitions on a very frequent basis, so much so that he was passed by on inclusion in a Mosconi Cup because he didn't have enough points from the European equivalent of the BCA.
On (c) how many Americans have been invited to invitational events in recent times? Two? Three? The WPA ranking points are not beneficial to American professional players as a whole. Two or three doesn't cut the mustard enough to warrant tournament promoters greasing the palms of the WPA so they can travel the world and enjoy banquets in Qatar.
You are right, though, in that there is no simple answer. However, the WPA does very little to help pool in general. Tournament promoters' money would be better left in the total purse for the event and put in the pockets of the pool players. They're the ones starving, not the WPA members. Tournament promoters are paying WPA members to travel the world, allowing them to receive the red carpet treatment wherever they step foot in, as if they're pool royalty. Meanwhile, do you really think the WPA would *ever* be instrumental in putting pool in the Olympics? It ain't happening anytime soon, and it sure as heck won't be happening in my lifetime. Probably, it will never happen, but I won't live long enough to find out.
Why do we need an organization such as this? Ranking points for what? Matchroom doesn't seem to utilize the WPA ranking points for the Mosconi Cup, and to date, the Mosconi Cups seems to be the event that every professional pool player wants the opportunity to compete in. Matchroom Sport would be a great governing bdy for professional pool around the world. They're fair, and they know what time of day it is. Plus, they put their money where their mouth is, unlike the WPA with a press release once a year, if we're lucky, about a banquet in Qatar.
The WPA is the Emperor in The Emperor's New Clothes, and those who follow the WPA are blindly following a Pied Piper, getting nothing in return, other than a brown nose.
