I agree....kind of. I was the parent represented in the bold/italicized/underlines sentence above when I was asked by a friend/parent that they thought my kid might enjoy/be good at it. Once I was in though (and my wife as well) we were HOOKED. The benefits of the sport have more to do with the intangibles (future success) off the mat that they do with winning on the mat.
Y2:
Gymnastics and swimming are the other sports. My belief is that the key is to get parents involved by selling the long term benefits of the sport (re: above) prior to entry. While there aren't EVEN CLOSE TO THE ELITE monetary success stories of these three sports as there is to the big three (basketball, football, baseball), the intrinsic benefits of involvement are not to be doubted. There just aren't a lot of "other than" high quality humans in this world who either wrestled, swam or tumbled.
IMHO
