So, let’s say you have a system where people go to work, do their job, and get paid. The employer wants more productivity, so the work becomes more stressful (“a full workload”). The worker does more for less, the company celebrates.

There is a hidden element here: stress. Your workers will be more productive, however their baseline stress levels will rise over time. It’s cumulative and takes years to show; but it means everyone above a certain age who works a well paying job has a high stress burden. A lot of people live without any job security.

Stressed organisms do not reproduce.
