Not going to get into a huge debate, but I disagree that it's a good thing or even remotely ideal. I don't there should be such huge separations in society to the point where you can point somebody out as "rich" and "poor" - especially pegging an entire neighborhood as poor or mostly poor.
We can do better to provide quality housing and the ingredients of dignity to everyone.
Employers may use credit report information to verify an applicant's identity and to look for signs of excessive debt or past financial mismanagement. Source: https://www.experian.com/blogs/ask-experian/why-employers-check-your-credit-report-and-what-they-see/

Good luck getting a job if you were ever convicted of a crime, no matter how innocuous, or even had a police report filed against you (for certain jobs with clearances) - with no convictions, evidence, or arrest. Even being arrested with charges dropped can disqualify you effectively.
And you better believe if you actually got arrested, every local newspaper has doxxed you - with full name, mug shot, even potentially your employment history and rough home address. All it takes is a name to get somebody's address because people search websites exist to compile all of the wonderful publicly available information.
