Occupy Wall Street was cleared out with tear gas, that's why it didn't work. The world has changed since the 60's; the press is much more compliant now, MLK would probably not have succeeded in the present environment. That's the problem with fighting power, you can't just keep using the same tactics over and over and expect it to work. Eventually the system adapts. Marches and rallies are completely useless these days- point to one thing the women's march accomplished, even though it was the biggest protest in us history.
