As I've posted before, airline deregulation has been good to the-now 300 million Americans and not so good for the several hundred thousand employees of the legacy airlines. Of course, 31 years ago, the legacies employed fewer employees than they do today, despite the widespread job losses suffered in the past eight years. But non-airline Americans have benefitted from much lower airfares (in real terms).
IMO, government has no place deciding which airlines can fly which domestic routes and determining the fares. Others will disagree. I think they're out to lunch, but everyone is entitled to their opinion.
And yes, I agree that the failing airlines should have been allowed to fail. For eight years now, the lifeboats have been overloaded - time to toss some out so the others might thrive. But sadly, that hasn't happened.
