The problem with OWS, in my opinion, is that they have no leaders. They're selling this as a good thing, 'equality is good' and all that, but in practical terms a movement needs leaders to keep things cohesive and on-message, to prevent things from fizzling out in different ways.
India had Gandhi, the Civil Rights had King, the Suffragettes had Pankhurst, not to mention the other lower leaders and organisers who didn't make as big a public impression.
There doesn't seem to be anyone centrally thinking about what's good capitalism and bad capitalism, what's the useful engine of change and productivity stuff, and which companies are exploiting their workers and the environment, conning their customers, and so on.
There needs to be leaders looking through the published accounts of big companies, look at which pay their ground-level staff peanuts so they can pay their executives millions, and target them, rather than generically target 'Wall Street' because that's where they understand capitalism as happening.
I'd like to believe that change is coming, but don't see it happening.
