Burger King isn't the be-all and end-all of the service sector - banking, insurance, telecommunications, and software are all service-sector industries. And they are industries where, not coincidentally, the US is the world leader. Really, proponents of manufacturing ought to wonder to themselves why, if manufacturing is so critical, we are still by far the richest country in the world, despite thirty years of declines in manufacturing.
The sky is not falling ;)
