You reminded me of something: a nurse in San Diego sleeping through her entire shift is more productive than half a dozen nurses in many third world countries working hard, because the way economists measure productivity is the $/hour output. People doing nothing in America are much more productive than people doing a lot in most of the world because that is how we define productivity, and how the term is discussed in articles and papers.
Doesn't matter, the same articles and papers will bring up that US enjoys higher productivity due to better technologies, etc, but since all of that makes it very hard to be really measured, it's always a mixture of some heterogeneous ideas together.
