Roger Waters' response to why people like "The Wall"
"I think people are sick and tired of being told that the most important thing in their life is commerce and the new this and the new that. I think people are probably ready to go now, 'Well, all of that rhetoric lead us to lob bombs over the top of the wall, that divides society ecologically, economically, philosophically and politically, from all our fellow human beings. And we no longer want to be told by our political leaders that they are scum and that we are great.' So that I believe that it may be we're no longer interested in the 'us and them' form of political philosophy that we've been fed on for the last couple of 1,000 years and that we may be ready to move into a new place. All that, plus "Comfortably Numb" is awesome."
