Will Wilkinson hits the nail on the head.
When Mr Hayes says that "very powerful interests will brand this as 'left' rather than 99%", he is right, if by "very powerful interests" he means "all the Americans who recognise that the 99%-er message is coming almost entirely from the left". This is certainly a large and powerful group, commonly knows as "Republicans".While on the topic of the 1%, it is interesting to know that the level of wealth (as opposed to income) controlled by the 1% is actually still significantly below levels in the 1920's and early 1930's.
