I don't agree with the authors' summary of their own graphs. If you look at the graphs, it's more like "cognitive distortions hit an all-time low around 1980, began slowly inching back up from 1980-2000, then accelerated more rapidly upwards after 2000, leading to a clear trend break by 2005 or so." I've also heard conflicting info about this and would like a more definitive analysis if anyone knows of one. I've seen people claim that total comp, including especially health care benefits, did not stagnate and continued to track productivity.
