But why does it work fine everywhere else ? It's not like we all follow the US model, yet our airports are fine and our airplanes dont crash over silly cost cuts.
There must be something the americans do wrong, somewhere, and optimisation cannot be an excuse for mediocrity. Do it fast and safe or do it slow and safe: the passengers can wait, or build their own planes and airports if they think they can do better.
Are American airports statistically less safe than other ones? Seems like you are assuming this is the case in your comment, but have you actually checked?
