It's an interesting question. We are all pool die hards (of varying skill levels from bangers to near-pros), and probably wouldn't want our kids to follow in our footsteps. Boxing parents might have a similar mindset. IDK how it is for other sports.
In Asia, the pressure must be higher? In Taiwan, where double world champion Wu, the Ko Brothers, Chang, etc, are all from, the priority there for kids is education and music. What must their lives have been like as kids and teens? What were their parent's lives like? Did they get ridicule from other parents for letting their kids "play pool"? Whatever flack a junior American prospect and his parents get must pale in comparison to a kid/parent from Taiwan. IMO.
