I think that's a bit reductive. Part of what's missing here is personality, or what I would call unique mediocrity. People who have no idea what they're doing just deciding to paint a wall yellow because they feel like it. The issue isn't just that some apartments have craftsmanship and others don't: it's that the high-skill and low-skill efforts look superficially the same.

Think about it with Marvel or Star Wars movies. There are some really good ones, and some really boring ones, and although you can definitely say "Thor Ragnarok" was better than "Iron Man: Age of Ultron", that doesn't change the fact that when you zoom out, it seems all we're getting is superhero and Star Wars movies, and maybe it would be nice to watch something else now and again.

We want more than just good craftsmanship. We need people of mediocre skill to be making things that are weird and interesting.
