i think this Guardian' article has not been posted (i made a search but i can be wrong), and it is really worth to be read. it is about the growing inequality, gap between richs and poors in US, and the difficulty to match the american dream with the reality.
because of copyright problems i remove the article but i strongly encourage you to read it there :
