One clear reason for these disproportionate imprisonment rate can be tied to poverty and social structures. In particular, a pronounced weak attachment to labor among many working-age adults in black communities has fostered a common experience of poverty and economic hardship. Ultimately this has served to create social spaces where bonds of family and community begin to fray and fall apart. These types of environments have created higher levels of juvenile crime, drug use, and even violent and gang-oriented crimes. Although white Americans too have a history of living in poverty, the average national rate of family disruption and poverty among blacks is two to four times higher than among whites. Furthermore, another reason for the United States racialized prison system can be seen with the war on drugs. Despite similar rates of drug use among blacks and whites, blacks make up 50% of those incarcerated for drug use compared to only 26% of whites.
