The Occupy movement nationwide is an anarchist attempt to collapse our economic system. They have no leader and no purpose beyond lawless chaos. The movement has attracted attention and participation because it strike a chord in people's hearts against "the system," or "the man," but in the end they are protesting against people who have no power to change things.
One example of the ineffective nature of OWS is the extreme amount of civil disobedience and public destruction. If they had a unified message and a real purpose, they would not need to resort to rioting, rape, and theft to speak.
The original message was a protest against "the 1%" who the protesters see as unfairly owning and controlling all the wealth, but they had no plan beyond shouting "This is unfair!" The concept that the financial pie is finite and you can only increase your wealth by stealing it from others is a fallacy, but it is one that many people buy into.
We are now seeing the cities and towns across America getting fed up with the lawless protests, and starting to crack down on crime and public disturbance. Local businesses have been vandalized or forced to fire employees because the protests interfere with their day-to-day trade.
Ultimately, the OWS movement is having no effect on public policy and no effect on Wall Street or "the 1%" beyond nuisance. However, the victims of violence, theft, and rape have been affected, and I cannot imagine that they will be sympathetic to furthering OWS in the future. It is burning itself out under its own failure to self-control.
