Reddit reviews Racial Taxation: Schools, Segregation, and Taxpayer Citizenship, 1869–1973 (Justice, Power, and Politics)

This is the type of mindset that allows for something called "de facto segregation." It has existed in rhetoric in the Jim Crow South but was actually perfected by the North and remains today. Structures were created from "on high" to "aritificially impose" segregation and these structures and their effects still exist today. Hoping they will just disappear "organically" is wishful thinking that allows inequality to exist unopposed.

This book is a good place to start on the subject.

However, since I know people have lives and don't necessarily have free time to sift through textbooks. Here's about an hour worth of podcast introducing the subject. The majority of people I see on reddit who begin this discourse don't even understand background information like this. The American education system has done an amazing job at convincing its youth that Brown v. Board of Education was the nail in the coffin for segregation and once you're indoctrinated into that belief it becomes obvious why the highest upvoted comments on threads like this exist.
