Want to understand why the United States functions as a racialized caste system and see how this affects your work? This lecture reviews major historical policies that organized citizenship, housing, environment, education, employment, healthcare, criminal justice and marriage. I show how policies in each area become an interlocking web where people of color experience hurdles far beyond interpersonal racism. I demonstrate that these collective hurdles result in challenging outcomes in every social institution. This course should be taken before more advanced courses about interpersonal racism or workshops that discuss what you can do.
