On June 26, 2025, Chicago firefighters responding to an arson found their aerial ladder would not deploy. After restarting the rig — a one-minute delay — four people died, including a pregnant woman, her five-year-old son, and her sister who threw her child from a third-floor window before perishing. That malfunctioning truck traces back to how private equity transforms essential infrastructure into profit extraction machines.

Two decades ago, more than two dozen independent manufacturers competed to build America's fire apparatus. Today, three companies control approximately 80% of the market. REV Group — owned by private equity firm American Industrial Partners — systematically acquired former competitors including E-One, Ferrara, and Spartan. The result: a $4.5 billion backlog, four-year wait times for custom trucks, and ladder trucks now exceeding $2 million. Profit margins tripled from 4-5% to over 13%. Senator Josh Hawley called it a "heist" at a September 2025 hearing. Four cities have filed federal antitrust lawsuits.

The playbook extends beyond fire trucks. KKR controls significant ambulance market share through Envision Healthcare and Global Medical Response. As PE's air ambulance share grew, median transport charges increased over 60% between 2012 and 2017. The fire truck case is simply the most documented example of a pattern: acquire, consolidate, reduce supply, extract margin — with customers having no alternative but to pay.
