This is somewhat like saying the person who pulls the levers is responsible for the productivity of a factory. Have productive gains in the last 20 years been that high? It seems like mostly a roll out of productivity gains from the digital computing/processing and communications hardware which came in a rush 20 years ago and has been incrementally improving since then. They just did a poor job of capturing the benefits from their new hardware. Other than Apple and a few others perhaps. Maybe Qualcomm? This is why it's good to go vertical like Amazon.
