....and if they do, they can expect the passenger's lobby to become quite aggressive in highlighting the adoption of profit over safety. Now, that may or may not be effective, but what then happens when the next accident occurs in the regional industry with low time pilots in an error scenario ?

Congress would be barbequed and would likely be the coup-de-grace for regional carriers using low-time pilots.

Besides, all such a roll back would do would be to provide a temporary relief to the industry as the real problem ISN'T the higher experience minimums, it's the combination of excessive cost to obtain a crap job that pays like garbage and provides even worse treatment. People aren't interested in that anymore, when they can make much better $ in other industries and get treated 1000% better while doing it. It's going to get to the point in 6 or 7 years where even the legacies will have a pilot shortage as all the present regional pilots will not be accepted and the regionals will be just about dead at that point.

That's what ultimately happens when you turn a once respected and difficult to obtain profession into nothing more then that of "just another job". They've patted themselves on the back for the ability to decimate this profession and the chickens are coming home to roost.
