They are protesting against the system. That is why their slogan is "We are the 99%". Which implies that the 1% are the enemy of the 99% (which they are), 1% of Americans own 40% of the wealth and they caused the crisis and got richer from it.
The reason they don't have demands, is because demands focus on a particular symptom of the system, like joblessness. However it is the system itself that is the problem. They are very aware that the rich are rich because the poor are poor.
Slogans such as "The system is not broken, it was set up this way," points to their opposition to the entire capitalist system.
Like the roots of the tea party, they are protesting bail outs for large companies and the wall street greed and corruption that ruined America. A lot of them went to college and did everything like you are supposed to but now cannot find jobs or cannot get loans to go to college.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
