I would say that ATP and the likes contibute to the number of people, but there are other feeders too. Hang out with some Daniel Webster, ERAU or other Aviation College guys and all they think about is jets. Most of them would give everything but their left nut to fly a jet. And the only reason that they wouldn't give their left nut is becuase the college that they went to already took their right nut, and if they gave up their left one, they wouldn't be able to beat off to the poster of the CRJ (or even worse a 1900) they have hanging in their dorm room.

There will always be someone that lacks the self respect that will fly there just to do it....
