Right on the money....was just thinking the same thing. In my travels and living around the world in my military career, I also saw poverty but never the arrogant, lazy, belligerent, hate-filled, gimme-gimme residents that I see here in the US. And I am talking all races and ethnicities. IMHO, the breakdown of the family unit and a strong father figure in the home is the main cause of this culture rot.
You left out-fat!
Very good point, but there's another factor that's actually very ironic: affluence.
Let's face it ... The kind of mentality you describe in your post and that you see on full display in rioting scenes in Ferguson would never be seen in most places because only an affluent society could ever tolerate it. In almost any other society, people who are so useless and emotionally stunted would have been cast out into the wilderness or tossed into volcanoes years ago.
