Americans get upset about behaviour on flights

Having recently traveled in the USA, I was amazed again at what Americans take for granted they can bring on as carry-on luggage. As I scrabbled for space in an overhead locker, I thought no one seems to mind that the guy behind me stuffing in and overhead locker half a house load. Apparently, I am not the only one:

Now I see passengers jockeying for overhead space wearing pajamas and flip-flops, and sometimes it looks as if their clothing hasn't seen soap and water for a very long time. They're all lugging on everything they own in a steamer trunk or a Hefty trash bag.
