Privacy and space for Suva residents

from w
When I visit Suva I notice so many contrasts in how people use space. Some houses are so well secured for privacy and safety from theft and others are small, crowded flats. Here is a house in a Suva suburb with high security, and the other picture is of a bunch of kids doing their maths homework, all arms and legs touching, feet almost in your face. There's a different concept of space and privacy that surprises some vavalagis who are used to keeping a distance. Is privacy and space to do with wealth or to do with cultural norms?
