Productivity measures how much output is created from a given amount of labor, capital, or time. It is one of the deepest drivers of long-term economic growth because societies get richer not merely by working more, but by producing more value per unit of effort.

That is why tools, training, systems, and innovation matter so much. Higher productivity can raise wages, lower costs, and improve living standards. It is the quiet engine behind prosperity.
