Robotics deep dive: THE LABOUR SHORTAGE, CHECKED Apptronik's homepage says Apollo helps "address critical labor shortages in industries requiring manual, physical labor." Some version of that sentence opens nearly every humanoid pitch. It is a checkable claim. A shortage of workers leaves a signature: employers competing for scarce labour bid the price up, so real wages rise in the affected occupations, openings stay high, and quits stay high because workers with options keep leaving for better ones. US warehousing and storage, production and non-supervisory workers, in constant dollars: $23.14 an hour in 2017, $26.06 in 2026. Up 12.6% against 8.2% for the private sector as a whole. That is a real relative gain and the vendors are entitled to it. Through 2021 and 2022, the tightest labour market in fifty years, warehouse pay rose 9.1% in nominal terms and 1.1% after inflation. And the sector went from 1.23 million workers in 2019 to 1.85 million now, adding 620,000 people while describing itself as unable to find them. Manufacturing runs the other way. Real production pay was $28.45 in 2017 and $28.88 in 2023: 1.5% over six years, spent entirely inside the loudest years of the shortage story. Against the average private-sector production worker, manufacturing paid 95 cents on the dollar in 2017 and 91 cents in 2022. The second half of the signature agrees. Manufacturing job openings are running at 3.70% in 2026, against 6.22% in 2021 and 3.54% in 2018. Quits are at 1.32%, the lowest in the decade I pulled. Workers have stopped leaving, which is what a labour market looks like when nobody is bidding. The 2.1 million figure everyone quotes comes from the 2021 Deloitte and Manufacturing Institute talent study. Its actual sentence: without changes to the skills composition of the workforce, manufacturers "could leave up to 2.1 million jobs unfilled between 2020 and 2030." The Manufacturing Institute is the workforce arm of the National Association of Manufacturers, and one co-author is NAM's chief economist. A conditional upper bound about training, quoted as a vacancy count. The demographic case is the strong version and it is true. Japan's working-age population peaked in 1995 at 87.5 million and is 72.9 million today, down 16.7%. Germany's peaked in 1997 and is down 6.2%. South Korea's peaked in 2018 and has fallen 3.4% in six years. The US working-age population has never been larger: 220 million, an all-time high in 2024. The demographic argument is correct, and it is an argument about Japan, Korea and Germany on a twenty-year clock. The purchase orders it is being used to justify are being signed in the US this year, in occupations where the wage data says nobody is bidding.
