What you're describing I've seen referred to as "hedonic adaptation". DW and I were just discussing this. She has friends from her artistic endeavors who have somewhat less than we do, and so she has a more nuanced sense of how privileged we are. Me, on the other hand, though I grew up kinda poor, that was a long time ago, and these days most of my friends and business associates are at least as well off, often orders of magnitude wealthier than us, so our situation feels like no big deal most of the time. That plus we live in areas full of extremely well off folks - I tend to "complain" that on our road we're the trailer trash. Sometimes perspective is hard to come by.
Lol, I used to call it "Hedonistic Creep," but "Hedonic Adaptation" does sound a lot more tasteful
I used to think of it in even minor instances, such as how the first time I had a car with power windows, or the first time I lived in a home with central a/c, or when we first got cable tv with a few movie channels, I felt "rich" for a little while. But then it just felt normal, and instead of feeling elevated somehow, I just started looking at crank car windows, window-shaker a/c units, and over-the-air tv as a step down.
The whole power car windows thing just gave me a funny flashback. Nobody in our immediate family had bought a car with power windows until the fall of 1984, when my grandparents bought a 1985 Buick LeSabre Limited that was probably about as fully-loaded as you could get (although no leather or sunroof). Over the summer of 1985, Granddad bought a new C-10 Silverado pickup, that, for a truck at the time, was pretty well-loaded, with power windows and such.
Well, the fall of 1986 comes around, and Mom bought a new, but leftover, Monte Carlo. When Granddad saw it had crank windows he joked "Oh, you got a CHEAP car!" He was just joking, and I remember thinking it was funny at the time, but ooh, was Mom STEAMED!
The 1985 model year seemed to really be the turning point for us, when it comes to power windows. My paternal grandparents bought a 1985 LTD, one of the small, Fairmont-based ones. First power-window car. It was followed by an '89 and '94 Taurus, both with power windows. With my maternal grandparents, that LeSabre and Silverado were the last vehicles they bought. And after that Monte Carlo, everything my Mom and stepdad bought from there on out had power windows.
It's funny how power windows are expected in just about everything these days, but once upon a time, they were a plaything for a rich. I don't think you could even get them in small cars until probably the mid 1970s. Chrysler never offered them in the compact Dart/Valiant as far as I know, so they probably started with the 1976 Aspen/Volare. I doubt any Ford Falcon or Maverick ever had power windows, although I'm sure when the Granada came out, it offered them from the get-go, as that was a "luxury" compact. And I doubt if Chevy offered them in the Chevy II/Nova at first, although once the Granada came out, they probably upped the ante and decided to offer them.
