Relatively speaking, it is not so huge compared to other nations. Just look at the title of this thread and result. This would not even be a valid question if this forum is based in Russia, China, Korea, etc.. And the polling result would be resounding yes. Take Korean LPGA players for example. All top players main goal this year was to climb up the world golf ranking so that they can qualify for the Olympics. Sei Young Kim cited the Olympics as the main reason coming to LPGA this year where she can improve her ranking more effectively.
Almost doesn't count
Good point. I was responding to the post that mentioned that kids are better younger than they were in the past. I don't have any statistics to back this up, so I could be completely wrong, but anecdotally it seems like you hear of more young men and women retiring at earlier ages when they start competing professionally in their teens.
