Racism and ethnic differences allow the power structure to exploit the masses of workers in this country, because that's the key by which they maintain their control. To divide the people and conquer them is the objective of the power structure. It's the ruling class, the very small minority, the few avaricious, demagogic hogs and rats who control and infest the government. The ruling class and their running dogs, their lackeys, their bootlickers, their Toms and their black racists, their cultural nationalists - they're all the running dogs of the ruling class. These are the ones who help to maintain and aid the power structure by perpetuating their racist attitudes and using racism as a means to divide the people. But it's really the small, minority ruling class that is dominating, exploiting, and oppressing the working and laboring people.
