How do you feel about a revolution?

Either if you imagine it or actually think it should happen. Is it time? Would it be good for the world to have a revolution now? I mostly think in the west, Europe and US. The thing is, for me, it seems like the politicians say that they will make things better for the third world and that we can fix the enviroment if everybody pitch in. But we'r being held back by something. Things don't seem to change.

I've been thinking about this since my teens. Is it just stupid faith to think that a revolution is in order? I'm not talking the french recolution here. Just a takeover of the power. I think we can feed the world and give them wealth if we wanted to.

I'm going to stop now. This is an idea. But I bet I would be in.

EDIT: some grammar. I'm not native to the english language.
