Actually the American working class does not willingly give authority to the capitalist class and its government. That government and system maintains its power through lies and all kinds of coercion from economic survival to direct repressive violence against workers and others who fight back.

Likewise the German people were the first victims of the Nazis. The capitalist class of Germany put the Nazis in power to crush a rebellious working class.

Violence against the innocent people of the World Trade Center was a crime. The fact that a few of the many were not innocent in their roles with finance capital does not change this.
