Opening

For almost all of history, work was organized around tasks tied to nature. Working less meant going hungry.

People’s willingness stayed the same. What changed was the ground beneath them.

The wealth generated by humanity has soared over the past few centuries while weekly working hours have steadily fallen. Both happened together because each hour of work began producing more value.

That is what we call productivity, and the definition matters more than it may seem:

Productivity is producing more value per hour. Working more hours or burning out more does not count.

The same worker produces much more when surrounded by better tools, infrastructure, energy, planning, and organization. Three engines explain almost everything: physical capital (machines, roads, energy), human capital (education, health, knowledge), and an invisible layer of organization and institutions.

As these engines improve, each hour generates more value, creating room for fewer hours, higher wages, lower prices, or more profit. Without productivity gains, there is no broad way to reduce working hours without becoming poorer. With high productivity, working less becomes a real possibility.

This entire training depends on this idea: productivity is a property of the environment, not a virtue of the worker.
