How can economy grow by shrinking?

I was riding in a van near York, Pa. last week when one of the passengers pointed with pride to a giant new facility owned by a major grocery chain and announced, "That's going to be their regional distribution center. It will be fully-automated, requiring only about 10 people to keep it running day and night. It will replace a distribution center that requires more than 100 workers."
