>> It's not the managers or capital owners that have been driving these productivity gains either > I'm under the impression most of the productivity gains since the early 1990s were due to large capital improvements, which aren't paid for by employees. Expanding here, the improvement in information and communication technology (one aspect of capital investment) has dramatically increased the effectiveness of intelligent management at the top. They have vastly more signals, and vastly higher granularity, with which to make decisions. I don't have data one way or another, but I could believe that managers' productivity-per-unit-talent has improved more than line-workers' productivity-per-unit-talent.
