[ezlejzxb] Layered societies and at large voting

In some locations, there exist multiple distinct societies layered on top of each other, living in geographically the same area but otherwise not mixing and barely interacting.  Most commonly class divisions in dense urban settings.

Such locations are not suitable for geographic-based political boundaries, i.e., legislative districts.  Instead better would be multiple legislators "at large" from a single district.

In contrast, geographical districting is useful to subdivide a very large area of homogenous society: the residents of each district can have a legislator who is physically close to them, perhaps for face-to-face discussions.
