In the last ten years many comparisons have been made between the productivity of British industry and that of its American counterpart. In his book We Too Can Prosper,1 Graham Hutton has summarized most of the results. He found that, in the early 1950s, the average US worker in manufacturing industry produced, on average, times the (real) output per period of time as his British counterpart; that productivity in the United States over the last half-century has trebled, while it has doubled in the United Kingdom; and that the US, with only three times the population of Britain and a smaller proportion of her labour force engaged in manufacturing industry, supplied half the world’s output of manufactured goods.
