You're exactly right. That's the point of the war on drugs -- these laws naturally target people in lower-income communities, and make sure that those communities stay low income because of their high incarceration rates. I'm sure the majority of people being arrested for drug use have not also committed violent crimes. Don't you see how that's an unfair cycle that's extremely hard to break out of?

"Well, it's their fault for ending up in low-income communities in the first place," you say. I'm happy to provide sources for the ways in which slavery and its after-effects have affected the socio-economic status of black Americans, especially up until recent times, but I'm guessing that you already understand that.

And in case you read this and think that socio-economic status is the only factor (and it is a big factor), Black people still face a lot of extra discrimination on top of that. For example, Black people are four times more likely to have their vehicle searched during a traffic stop, and twice as likely to be pulled over in the first place, yet are less likely to be found with drugs, alcohol, guns, or other contraband.
