Dodie Smith said this quote

And what I thought most about was luxury. I had never realised before that it is more than just having things; it makes the very air feel different. And I felt different, breathing the air: relaxed, lazy, still sad but with the edge taken off the sadness. Perhaps the effect wears off in time, or perhaps you don't notice it if you are born to it, but it does seem to me that the climate of richness must always be a little dulling to the senses. Perhaps it takes the edge off joy as well as off sorrow.
