Also, another aspect to consider is what is the basic minimum to be integrated in society and exist socially.

In the 20ies cars were not a social necessity, but beyond the 70ies, not having a car generally means partial social exclusion (more difficulties to get a job, etc).

Today, not having a computer/smartphone/tablet and an internet subscription would impact social integration.

This basic minimum need is not set in stone, it's a shifting target. Rephrasing the problem with "What is the current median revenue Vs What is the basic minimum to be an integrated member of society" would be a better way to put it.
