Did someone say "One Big Union"? Sounds like the IWW would be right up your alley. It's coming back to life again - definitely check if you have a local branch!
The IWW is an explicitly radical militant union devoted to overthrowing the tyranny of the wage system and settling the class war through full worker control of all enterprises. It's an entirely different animal than the bloated business unions who settle for a "fair share" of the profits. The IWW asserts that all of the value produced by the labor of workers should go to workers, and the bosses can just become workers like the rest of us.
Capitalists can choose to give up their property and become workers like the rest of us, or they can get the wall and then their property is redistributed. The capitalist class has colonized our society, and their enforcers are the police. And according to Franz Fanon's books on anticolonial struggle in Algeria, colonial relations never go away unless fought with anticolonial violence to oppose the violence of the colonizers. Ultimately, violence is what is needed to force those in power to give up their wealth, and if they gave up their wealth willingly then violence would not be necessary.
