Well i guess the more people that are angry, the bigger the problem is, until the have to acknowledge it. Yeah, the actual fact of holding signs, chanting, and raising hell is not gona change anything. But then again we can't just let all the world most powerful people gather and have a party with champagne, caviar and god knows what, while there is massive poverty even in the city (chicaco) that they are gathering, children dying of starvation, war, etc. Our lives are fucked up, so we return the favor.
A lot of people would like to protest but they say, the fact itself is not gona do anything. the easiest way to give up your power is pretend you dont have any.
Also, me, personally, I'm not going to do ANYTHING or start anything, other than defend myself. The average joe who owns a coffee shop should not get his shop savaged and destroyed. The policeman himself is probably brainwashed, or facing loosing his job and family income if he doesnt comply and follows order, so they are on the hook too. I will not throw the first stone.
