Those who accept Jock Culture values often go on to flourish in a competitive sports environment that requires submission to authority, winning by any means necessary and group cohesion. They tend to grow up to become our political, military and financial leaders.
It's interesting, and there's some truth in this. But I don't think looking at life through this lens is helpful. I'm most definitely a puke, and my brother is a jock. However, growing up, I had a good time with his social circle and he with mine. Pukes become leaders too, but I think it's more by creating structures rather than moving up through existing ones.
