As i hop between reading and writing, i ran across this Harvard Business School post titled, "Do Productivity Increases Contribute to Social Inequality?" I've certainly reflected on this and recognized that certain increases significantly do. I offer the minor case of my boss being fired and his work ending up in my lap, and extrapolate to layoffs across the US economy where the layoffs mean loading more work on the people who are happy to have a job as they consider the consequences experienced by their laid off colleagues. The revealing articles about the big warehouse distribution centers for mail order come to mind, where there are so many people waiting to for the jobs, that the employed put up with the horrible conditions.
The answer in the brief is, "Yes, but it's not necessary that it does," and refers to the following bibliography:
