They make a good point about workers not able to stay at a job longer than a few years. I'm sure this impacts productivity quite a bit. This article assumes that productivity is accurately being measured (GDP/worker hours) and doesn't address this issue. It would be interesting to see a breakdown per industry to see where the ups and downs are. I mean, you've got companies like google that generate a lot of money per worker, and they could do even more if they didn't invest in the future and only worked on stuff they had a monopoly for (search). Jobs have become increasingly specialized, I wonder if this affects the measurement of productivity.
