As an economic historian, I appreciate what manufacturing has contributed to the United States. It was the engine of growth that allowed us to win two world wars and provided millions of families with a ticket to the middle class. But public policy needs to go beyond sentiment and history.

A successful argument for a government manufacturing policy has to go beyond the feeling that it's better to produce 'real things' than services. American consumers value health care and haircuts as much as washing machines and hair dryers.

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.
