Upper class pigeons have more luxuries. The manga has a chapter with some of the more poorly off characters winning a trip to a bathhouse and counting the option of heated baths as special. The second game has an optional scene at a high class department store which sells hot water bottles and humidifiers. A very poorly off character seeing these describes them as "thermal frivolities".

As a Dove Party agent Yuuya has had a lot to do with the disadvantaged, too.
