We are all born naked and neutral. However, this neutral state is short lived. Our first experience in life is consumption related. Being cut from the umbilical cord, which we had been physically connected to and consuming from for the past nine months, can be seen as symbolic of the beginning of our life long journey of consumption.
We start by consuming food, then clothes (diapers), then shelter (crib), then entertainment (toys). As we grow, our consumption intensity increases (more food and more refined food), more clothes (a larger and more diversified wardrobe), and more sophisticated and expensive types of entertainment (Xbox, motorcycle, etc.)
