Why do we demand so much from our systems?

When I was in college a while back I was very happy with my system. I played records and I also had a cassette player from Kenwood. I wasn't interested in it sounding better because it was very satisfying.

Fast-forward to current times, Systems are more revealing and detail is a lot better than it used to be which I'm not sure is such a good thing. And I say this because it seems that as our systems improve as well as recordings improve we seem to be getting more demanding and becoming more and more unsatisfied with whatever we listen to.

Is it possible to be satisfied  with anything these days??
