I'll say one thing: ornamentation is harder to clean. If you're in charge of cleaning your own things, perhaps you desire surfaces that are easier and quicker to deal with. If you're in a position to hire people to do it, maybe you don't care as much. And I wonder if that's one reason for less ornamentation. There's also a desire for more simplicity, I guess as a reaction to the layers of complexity we wrap our lives up in, and again, perhaps ornamentation in that case becomes psychologically unsettling.
