Victorian economist Alfred Marshall argued that it was no accident that free societies and coal-powered industries are found together.
In 1878, Alfred Marshall, one of the most influential British economists of his day, looked back over a hundred years of social progress. For some, the French Revolution (1789) was the key, for some the Communist Manifesto (1848). But Marshall believed that what had liberated the people and raised their standard of living to new heights was not political idealism, but coal and steam.
