Kids in 300$ jeans are protesting the rich because they only got an iPhone 3GS for birthday instead of a 4S.
It is not about a change of society, about finding new values, about giving and helping, it is envy. Just like some people hate their neighbours because of their more expensive cars, janitors hate the professors because they get more appreciation and nerds hate the football players because they get more pussy.
"Why do I need to work for what I want and those people dont? Fuck 'em!"
The only difference to the neighbours, janitors and nerds is that you'll find far more people who are hating on "the rich". Living in warm houses, eating three times a day, having access to medical care, being able to waste their time on the internet, but "we are the 99%". This is not about politics, it's about ingratitude and greed.
