Smil examines the history of American manufacturing quantitatively, from the nineteenth century through its rise to global dominance and its subsequent decline in employment and in share of output.
The historical material documents what American manufacturing achieved: the development of interchangeable parts and the American system of manufactures, the assembly line, the mass production of consumer durables, the wartime mobilisation, and the postwar period in which American industry produced a very large share of world output.
His analysis of the decline separates several things that are usually conflated. Manufacturing employment fell far more than manufacturing output, because productivity growth reduced the labour required per unit. But he argues, against the standard account, that output growth has also been weaker than the aggregate statistics suggest, because the computer and electronics sector's hedonic price adjustments inflate measured real output for the whole sector while most other industries stagnated or declined.
His argument for why manufacturing matters covers innovation, since research and development concentrates where production occurs; the trade balance, since services have not offset the goods deficit; employment quality, since manufacturing supported wages that service employment has not replaced; and national capability, since a country that cannot make things cannot make them in an emergency.
The book is dense with data. Its measurement argument about hedonic adjustment is technical and is the part most likely to change a reader's understanding of the statistics. Smil is pessimistic about reversal and offers no programme.
Investors and policy readers who want quantified analysis of American manufacturing's decline and the measurement issues that obscure it.

Each book counts the physical inputs an economy consumes - joules, tonnes of steel, ammonia, cement - and establishes the historical rates at which past energy transitions actually moved. Those numbers let an investor size decarbonisation timelines and test claims about how fast an energy system can be rebuilt.
