The essence of capitalism is violence against the working class. This beating was very much like the racist beating of Rodney King in 1991. The cops represent the armed violence of the bosses' state. The terror that the police carry out against black and latin youth and immigrant workers is used to force immigrant workers as well as citizens to accept low wages, and mass unemployment without rebelling. The clubs of the police are meant to intimidate all workers.
Capitalists rule through violence against the working class.
Capitalism doesn't work. The rulers will never admit that their system can't provide the essential necesities of the workers, so they blame workers for the failure of their system. The US bosses have a profitable control of the Mexican economy, causing poverty and forcing workers to come here for work Borders are a weapon of the capitalists to divide the workers. But the workers don't need borders. We are one class all over the world.
