Yeah, gatekeeping and all that jazz, I agree there, but I'm going to go ahead and say that the average US college freshman student probably does not have it as 'tough' as the average US boot-camp inductee. I would extend that to the integral of 'toughness' over the tenure of the average US college 4th year student versus the average 4th year US service member, but it's more of a crap-shot with the Air Force ;).
