The Blue-Collar Crisis Breaking Big Tech: Inside the 349,000-Worker Deficit
Wall Street is modeling the AI boom as a software and silicon story, but deployment speed is governed by the physical availability of human hands. With MEP systems consuming 70% of data center CapEx, a 349,000 skilled trades shortage, orbital TIG pipefitting bottlenecks, and surety bonding limits are triggering $14.2M/month idle penalties across North America.
