With so much focus on worries about American products being uncompetitive with those produced elsewhere in the world and the associated impact on jobs and domestic economic activity, it is easy to forget that there are a number of manufacturing sectors for which American dominance has persisted for decades and shows very few signs of ebbing.
Perhaps the best example is the aerospace sector.
The United States currently accounts for half of global production (with Canada adding another 5%). While this share has declined substantially from close to 70% in the 1980s and 1990s, the reasons for the decline are mainly due to the expansion of Airbus (particularly since the introduction of the A320 in 1987) and consolidation in the U.S. when McDonnell Douglas merged with Boeing in 1997. The Boeing-Airbus duopoly has meant that North America and Europe accounted for nearly 90% of global production through to the financial crisis, although that has fallen to 82% today.
