The line at the impound lot was filled with poorer (looking) people, especially Somali, Hispanic, and Asian people for whom English was not their first language. My dad drove me there and stood in line with me, and I could tell it had a profound effect on his outlook. My dad has always been quite liberal, but being a rich, older white guy living in the suburbs, he hadn't seen firsthand some of the more subtle ways that poor / minority people are disadvantaged by the system.
