I don't have a comment on inequality generally, but what's your point specifically about a phone being a requirement? Toilets are also a "near requirement" in any meaningful sense that phones are a near requirement. But toilets (and sewage more generally) are obviously quality of life improvements over what humans had in previous epochs of history. Stated more succinctly: hasn't it always been common for major improvements in quality of life to eventually become the default, rather than the exception? Or am I misunderstanding your point?
