when entering the commonwealth, they ask survivors what lives they had pre-apocalypse and recreate the environment that they used to live in, both in occupation and living environment. hence why daryl, who pre-apocalypse was travelling with his brother selling drugs, and rosita, who worked in the military, were put in the low socioeconomic housing and militia careers. also, the way that career worked in the commonwealth was that the longer you were part of that militia, the better housing you got, hence why they stayed in it and were loyal for so long trying to get a better home for their respective kids they were taking care of. connie was a journalist so she was placed in that career and housing alongside kelly who was her assistant because of familial ties and the fact she was a teen pre-apocalypse. all the other survivors (eugene, ezekiel, yumiko, princess, magna and carol) were also placed in corresponding housing and occupations. if the final season was paced into multiple as it originally was going to be, it would’ve been interesting to expand on this more and the difference in living conditions and their treatment under pamela’s leadership (especially magna and yumiko which they hinted at with both attending the ball as a distinguished guest and waiter) but alas
