Collar: A massive, measurable shift is in progress from blue-collar to white-collar occupations, from man-hours to computer-seconds, from production to consumption, from saving to spending as the dynamo of the economy of high energy societies. In the mid-1940's there were 3 million more blue-collar than white-collar workers in the United States, but by the 1960's there were 5 million more white-collar than blue-collar workers. These trends are expected to continue into the 1970's. The Research Institute of America summarized the massive shift in these words: In northern Europe, where the soil must be cultivated rapidly because of the short growing season, the collar harness made it possible for the horse to replace the ox in the plow, and throughout much of Europe horses largely replaced oxen for hauling carts and wagons.The key part of the collar harness is a stiff padded collar with rigid projections (names) to which the traces or shafts are attached. The advantage of the harness is that the horse can push against the collar full force without impeding its breathing or circulation.
