If Katrina, Bush, America Invading Iraq etc. hasn't 'disabused people of the notion that America is paradise'; nothing I say will have a greater impact.

I may point out criticism of the US but it is a place where people can still come to and pursue their lives relatively freely when compared to other countries. The only class system in America is built on how much money you have which can make it possible for anyone to join as opposed to countries like the UK and France whose class systems are based on priviledge and which family you are part of.
