I think that's a little "cart before the horse" there. You can't have a game with an industry that makes money unless there are players. Players first, then the money.
Kids don't love basketball because the pro's make a lot of money. That's ludicrous. They are tought the game young, play for their schools, play in youth leauges and THEN enjoy watching the pro's which in turn brings the pro's the $$$.
Same goes for golf. There's Jr. Golf tournaments, lesson clinics at most public courses weekly. Again, people don't play golf because pro's make a lot of money doing it.
That is why I mentioned the PARENTS. In the 50's and 60's dads wanted their kids to be pro baseball players. Even if it wasn't 100% money oriented, (I mean the yankee clipper did have Marilyn Monroe

) it was a good goal to have a son be a great baseball player. The Williams sisters (from Compton CA, btw) had a father that pushed them into TENNIS, tennis, in Compton...? I already mentioned Tiger and his dad.
How many father's want to have their kids spending all their free time in poolhalls, with often times, somewhat seedy/shady characters? I know it can be done at home, and I know having a love for all things billiards isn't a recipe for a disastrous life, but I was putting a what would you rather question out there....
If parents have an interest in NASCAR, golf, swimming, heck, even MMA, there's a good chance their kids, being around it, will develop an interest in it as well; same goes with pool. But, as a parent, I would encourage MY kid to pursue interests that keep him out of the, um, less fortunate areas of town, and away from folks that may not have the kids' best interests at heart. Like many, I want my kid to have it better than I have had it, and really would like him to learn life lessons in a less harsh way than I had to growing up.... That may not have ANYTHING to do with sports, or other competitive endeavors, or it might. JMO is all.
The whole $$$$$$ part of my post was referring to seeing real promise in a young-un. More often than not, someone who excels in one thing certainly can in another. Most professional athletes had to choose a road at some point. John Elway was also drafted by the Yankees. Dave Winfield - all Big 10 in BASKETBALL. Babe Didrikson Zaharias could have excelled in ANYTHING. Jackie Robinson, Bo Jackson, Deon Sanders, Jim Brown, Jim Thorpe, etc. were mostly known for just raw athletic prowess, but getting there takes determination and a hunger, that could have propelled them to succeed in ANYTHING.
After all of my ramblings, what I was trying to get at in my first post was...would you want a kid that shows real promise in terms of natural talent and a strong desire to be great at something to put all his/her efforts into pool? Maybe you would....not me
