North Korea is an isolated bureaucratic state, much as the Soviet Union was from Stalin on. This is based on the false premise of Socialism in one country. In many senses this is little different than Hitler's fascist state.
Just because we live in the greatest country on the planet does not mean nothing here is wrong, that nothing needs to be changed. I attended an Episcopal church at one time...had I taken the perspective of "appreciate what I have" I would still be there, because at least they are a Christian church (they still have the 39 Articles in the Prayer Book) and they still read Scripture in services.
But I knew there was a BIG problem in the Episcopal church.
My point with all of this is not to say the USA is not great, because it is. Only that we have problems. Certainly you and I (actually everybody at this site) would agree there are problems with the USA. We certainly differ on what those problems are.

Grace is not common.
