Your knowledge is flawed. 

I did not say that money is what drives elite performance, but it is certainly a factor when you are a college student deciding whether to join the Greco Wrestling or football teams. 

I did not say that the successful women swimmers are in their forties. I said that women peak physically at 40. Yes, most successful female swimmers are in their late teens and early twenties. That is my argument. There is very little scope for a career in swimming, so once college ends, they are generally gone from the sport. Are you really going to argue that this statement is wrong?

"People and organizations driven by monetary rewards are rarely successful." Possibly. It is rare that a student from any given high school will get to the NFL, but that does not mean that the NFL does not exist. The NFL, by the way, is driven by money, and it is a very successful organization.
