The frustrating thing about many economic statistics, and this is talked about at length in "The Second Machine Age", is that they include very little of things we would deem very important. So things get "mathematically worse" but in reality are quite a bit better.
I don't want to go at length on this and beyond what my memory can recall, but an example they used in the book is Wikipedia. It's incredible obviously. But it does not factor in any quality of life or GDP statistic.
