This post is taken from my post at Grist.org that I put up a few months ago.

Rebuilding the manufacturing sector would not only provide millions of direct jobs, it would transform the entire economy, because manufacturing is the foundation of an economy.

No large nation, not even the U.S., can survive by only producing services. The vast majority of services consist of the economic activity that surrounds manufactured goods. In order to see why this is so, we need to take a stroll through the main sectors of the service economy; consider this an exercise in economic natural history.
