The majors will start to care when half their flights (which are 'regional' flights) can't operate anymore at the current pace because the regionals can't staff their airlines.

I'm not against the ATP thing but this could have some unintended consequences. It's not like people are just going to go out and buy 1500 hours of time and the appropriate amount of M/E time to get an ATP and there aren't really enough of the right kind of jobs to build that time with either. There may be enough folks out there floating around right now but in a couple years it could be very, very difficult to find adequate numbers of pilots. That's when the majors will start to care.
