There is a tale I like to tell people in the banking industry about change. According to a family legend, one of my mother’s aunts was Henry Ford’s neighbor in the early 1900s. Her husband was a successful businessman, and one day Ford asked them to invest US$100 in his Model T automobile. This was equivalent to about $18,000 today—not a small sum to give a neighbor with a harebrained idea. My great-aunt and her husband evaluated the opportunity for some time, and then told Ford no. They sincerely believed no one would ever buy a car; there was simply too much infrastructure supporting traditional means of transportation, and consumers were clearly quite comfortable with their horse-drawn wagons. In other words, they made a rational business decision, based on observations of consumer behavior, the business environment, competition, labor, and demand.
