This is my unique observation or view, not gleaned from mass media.
The above drop in productivity is actually a very good sign of growing jobs. It’s pretty simple. The opposite of that in INCREASED productivity, a negative sign, for workers. Same amount of work with less workers.
For example, if an employer lays off some of the crew, for lack of profit, the remaining crew has to work harder, and the financial mass media considers it an increase in worker productivity.
When profits are up, and the boss can afford to hire his brother-in-law, or employees can get their friends in, productivity per employee drops. Same amount of work, with more profit, and more employees.
