alt Hacker NewsBy "luxury" I mean approximately "anything beyond bare survival". My point is that the vast majority of material possessions have become absurdly cheap by historic standards. However that doesn't preclude severe societal dysfunction (housing, children, retirement, or as you note doctors and dentists).
Thank you for clarifying. It is true that many of such possessions have become incredibly cheap (and therefore affordable) especially when it comes to media consumption and other forms of escapism, but they do very little to address our fundamental needs (physical safety & health, financial security, emotional stability).
True luxuries (not having to worry, not having to waste time) are increasingly out of reach for most people.
