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.
