I believe that the latter movement was the most significant one, as it left a deep mark on the lifestyle of the United States. It led to the development of extremely large supermarkets. It also made owning a vehicle vital. Finally, this change also led to the rise of a "commuter culture" and to the disappearance of housing in the center of major cities.
