"Perhaps the most damaging single proof of this American superiority in all-round productivity lies in a comparison in September 1954 between steel output at the Inland Steel Company, Chicago, and the more modern Port Talbot plant of the Steel Company of Wales. For Inland produced about 260 ingot tons per man-year as against about 160 ingot tons per man-year at Port Talbot. It was a foretaste of the even more horrifying comparisons in the 1970s, 1980s and 1990s between productivity at identical car plants in Britain and on the Continent."
