A few things, it will be much larger of a "small percentage" of regional guys going to majors, thats where they will be getting most of their new-hires from. It's like these really low paying PR jobs in Manhattan or a "starving actor", you put up with the bull**** for a long time hoping to "get a break".
Kind of contradicting myself but I think if you keep persistent, the road to a major, though long and hard, is certianly achievable
