Anyone who has ever worked in a restaurant knows that the working class of the United States is an international working class, composed of people from all over the world: immigrants, refugees, second-generation Americans …. This is the direct result of US imperialism. The US maintains large parts of the globe under its domination in order to keep wages down and the price of raw materials and land low. This domination takes many forms – war, austerity, low levels of development – all of which result in the flight of workers from their home countries to the US.
