I'm not sure that the "Occupy Wall Street" movement compares very well to the Civil Rights movement of the 1960s in America.
First, the "Occupy Wall Street" movement does not really have a clear cut purpose nor do its leaders seem easily identifiable. I have yet to see a Martin Luther King, Jr. figure emerge in the "Occupy Wall Street" movement.
Also, the "Occupy Wall Street" movement does not appear to have generated as much sympathy as the Civil Rights movement nor has it generated as much of a following as the Civil Rights movement. The "Occupy Wall Street" movement seems to be generating more sympathy for local store owners and governmental agencies who have do deal with the unruly protesters.
The Civil Rights movement drew national attention because everyone could see clearly the discrimination against and oppression of African Americans (e.g., separate water fountains; seats in the back of buses).
The abuses about which the Occupy Wall Steet movement seems to be complaining are not as readily remedied as the abuses suffered by African Americans. Allowing everyone to drink from the same water fountains and have the same opportunities at seating in public places is one thing, but solving the problem of an unequal distribution of wealth in America seems far more complex.
