Hoo, boy; where do I start?
I agree with pretty much everything that's been mentioned so far.
One thing that particularly grates is the general loss of civility.
For example, I think I've read at least two news stories in the past couple of weeks about people melting down in airports and physically attacking gate agents because their flight was canceled or some such inconvenience.
I haven't witnessed such an incident in person—yet—but internally I am losing patience, fast, with that kind of behavior.
