No we can't have revolutions in this day and age. Just look about 12 or so years ago in Ontario. Unions tried to do something like this to protest agaisnt the PC goverment at the time. They called it "Days of Action" and shut a city down because the goverment was making too much cuts to welfare and other soical polices.
What happened? People cried, they complained, that thier life was being disrupted, and said the uninons and or people had no right to shut a city down to protest. This is basically like all over North America. Not too sure about Mexico so I should say Canada and United States. As long as it doesn't effect them, people don't want to do anything. Espically if you are Canadian. No matter what the goverment does, raise taxes, all we do is Cry, complain and do nothing about it. And if someone tires to do something about, us Canadians just complain about the people who are doing something about it.
So no, at least in North America you can't have a revolution. Now if you talk Europe, maybe. I like how in Greece and France, the people are not happy they can shut down the entire country, and then the goverment listens.
