Hmm. I think a lot of people are aware that GDP has its shortcomings. I think many would embrace a metric that fully captured well-being in an economic manner, but I didn't see the author suggesting any new metric that we should be following instead. I think we use GDP because it's the easiest thing we can use that isn't subject to [much] interpretation. And yes, that sometimes leads to problems.
