"Economic growth in Australia did not require the incorporation of a backward, unproductive rural sector. When farming later developed on the pastoral runs, it was commercial farming. Australia, as its greatest historian Keith Hancock said, was born modern. The United States, by contrast, imitated to an extent the history of Europe. In areas which had been self-sufficient there was more regional variety in speech and habit. There were pockets of settlement which for a long time remained outside the commercial world, even when access to it became possible. Backwoodsmen, hillbillies and country music were the results."
