A question that has been asked before but I don't think you've really answered. Assuming that you get the socialist majority that you're after, do you really feel that the rich are going to say "ok fair do's you win here's all our wealth and power"? They're going to make a last stand, aren't they.
So on the one side we're going to have the socialist majority with right on their side and on the other we're going to have the army, navy, airforce, fighter bombers, helicopter gunships, tanks, missiles, teargas, drones and all the exotic weapons our governments have been working on for just such a contingency. Good fucking luck on the barricades.
So we have a state that would unleash terror on its'own' people if its power over them was challenged. I would have thought that woud be a prime motivation to eliminate this institution. Or are we better off meekly submitting saying "sorry the world and all of us on it are yours guvner, what must we have been thinking".
What the capitalist know and in the main workers don't is where all the power lies in society, it is embodied, all of it in us the working class, because we do all the work in reproducing society day to day, and we have to be kept on-side, we have to see capitalism as being legitamate. We are told that we live in a democtatic society and we've used the democratic process and have voted for capitalism therefore giving it its precious legitamacy.
What if in the future an organisation of workers commited to peaceful democratic revolution gathered enough mass, enough momentum to trouble the ruling class, and of course this idea would naturaly be known by the working class by this time, it would have its social currency. What could the ruling class do? If it was an organisation like the WSM it couldn't corrupt or imprison its leaders because there wouldn't be any. If it took out prominant members of the organisation, suspended democracy or any other steps to deny it its voice, the state would be seen by workers clearly as the ruling class's intsrument of oppression, see it for exactly what it is. And so the state, and the class it serves would loose this essential legitamacy. Buggerd if they do and buggerd if they don't.
What of these humans who you reckon will be ready to impose this terror upon us? The armed forces, the police etc, are workers in uniform, wage slaves like the rest of us. I just can't imagine these workers in uniform obeying any order that has them brutalising a peaceful democratic organisation made up of people they might know or people like those they know and identify with.
It's worth considering that at the time of the Tianmen Square confrontation the local troops were not used, soldiers from a rural province the other side of China who spoke a completely different language were brought in to do the states dirty work.
I thank you for your wishes of good luck on the barricades but why have barricades in the first place? If you have an opponent and we do, the best place to attack is where they are weakest. If we try to overpower with force of arms we attak where they strongest, which exactly where they want us to strike. Democracy is their soft underbelly exposed at times of elections, we figure we should strike there.
