You are mistaking ‘quality’ as meaning expensive or exclusive. The normal Roman ceramics that ordinary people in the empire ate off and carried water in was higher quality than post-Roman examples. In Britain’s case they literally stopped using pottery wheels. Having well made vessels for cooking, storing, and transporting is a direct material concern for poor people.
It shouldn’t be assumed that the loss of an imperial figurehead ushered in much masterlessness, where rural roman elites remained so did their tyranny. The foederati kingdoms did not oppose slavery and often made romans second-class, roman poor went from having less protections than the rich to having even fewer than other types of poor people.
You also shouldn’t interpret stone buildings as a rich class signifier or oversized. Poor people did and still do live in stone (though my bad leaving out brick, those were important too and also declined in quality).
on sanitation, like there still were people in urban concentrations, they just stopped having clean water. That’s not good!
I guess it’s a trend that people that don’t need to work look for weird jobs, I heard of one that worked in the mailroom at an office building.
He probably just enjoys you & your coworkers company lol
