Place referred to North America and England which each had unique opportunities and constraints. Labor referred to what opportunities and constraints faced the person hiring or seeking labor and the person potentially being hired or sought. Soil referred to what grew well where and under what conditions. In essence, there were 2 classes of people in dynamic struggle where they each have something the other wants, but they each also have constraints on what the other wants.
