More than anything else, race can limit one's opportunities. America is still overwhelmingly run by whites, and their perceptions of others are often based on race, religion, sex, wealth, appearance, and personality. If you don't meet the white person's internalized standards of "acceptability", you don't get the job, the apartment, the bargain, the education, and a variety of other opportunities that could have helped you achieve the American dream. Just like in A House Divided when they had cameras on and one African American and one Caucasian Man went to see an apartment on different days in the same week he had two apartments available for the white man but for the black man no availability at all. We as a society need to change race discrimination because if we don't who knows what we are setting ourselves up for.
