EU here... Housing in the city is so expensive that minorities can't find a home there. Hope that helps.
So they end up living in slums. Cities have slums we just don't like to think about them. Occasionally right wing media will talk about them because there's a lot of Filth and crime like you would expect when everybody is dirt poor and being abused. Although honestly they don't even really bother with that anymore because they found they can just make shit up about actual nice cities and right-wing idiots will believe literally anything.
I mean they had a guy on Fox News pretending to be antifa who literally is the same guy who was pretending to be a violent black lives matter protester a few years ago. That is the level we are at people.
The hilarious thing is that the suburbs aren't sustainable. Even though people in the inner city make very little money and get treated like shit there's a lot of them because of how well, population density works and so the poor people in the inner cities subsidize the well-to-do people in the suburbs. Without the subsidies the suburbs can't pay for their roads in schools and cops.
It's basically an elaborate way to keep some form of slavery going even though we're not technically allowed to do that anymore. But again it's not sustainable because we are gradually breaking down the economy so much that there just isn't enough money to go around anymore. Capitalism is being dismantled in favor of a weird feudal system that benefits the very very top 10,000 or so people on the planet
