That includes everything

If everything is a privilege, the term loses it’s meaning. It just becomes a source of guilt rather than a recognition of social deficiency.

When I see the term used effectively, it is describing social conditions not biological conditions.

You’re privileged to have an access to low interest credit that lets you buy a house, not the house itself. A country like South Africa or Cuba or France with universal credit (or better yet, universal housing) doesn’t have this special privilege afforded to a subset of homeowners.

You’re privileged to live in a neighborhood that caters to people with good vision (car culture, lots of signage for navigation, etc). A country like Japan or Russia, with urban infrastructure dedicated to alternative navigation, isn’t specially privileged for the sightless.
