This chapter tackles the issues of mass incarceration and aggressive policing, and their impact on low-income communities and people of color. It places Trump's defense of police and denigration of Black Lives Matter into historical context. The chapter connects the rise of the carceral state with an ideology that pathologizes poverty, blames working-class and unemployed people for their failure to get rich, and defines an urban “underclass” as the problem. In this context, the chapter analyzes Trump's reverence for police as the “thin blue line” that separates civilization from chaos. Focusing its attention on the intersection between class and race, the chapter unpacks the logic that has motivated a long-standing effort to shift power and resources away from the working class and toward the corporate elite. It argues that liberal antiracist arguments misunderstand the class relations that underlie the current system of policing. The chapter concludes that labor groups have a crucial role to play in fighting police abuse and mass incarceration.
