The most addicted family-as-a-whole to the screens I know of live literally 100m from each other (3 generations). Suffice to say this is far from their only addiction. What you describe is certainly true for some people, but I am having hard time believing this is majority. I live long term far away from family and an occasional whatsapp video call is covering our digital meeting needs.

Most people are simply too weak mentally to resist various self-forming addictions and don't care about these topics at all.
