Private equity bought America’s essential services

私募股权如何买下了美国的关键服务

When a fire truck fails to deploy in a burning building and four people die, the cause isn’t just mechanical failure. It’s a business model. On the night of June 26, 2025, firefighters on Tower Ladder 14 raced to a Chicago apartment building where an arsonist had poured gasoline on both stairwells. When they arrived, the aerial ladder would not go up. The crew had to shut the rig off entirely and restart it. The delay lasted approximately one minute. Four people died that night — including a pregnant woman, her five-year-old son, and her sister, who threw her own child from a third-floor window before perishing herself. Nobody told the surviving family about the ladder malfunction. They found out from journalists. That malfunctioning truck is a thread. Pull it, and what unravels is one of the clearest illustrations of how private equity — the $9.4 trillion industry that quietly controls roughly 11,500 American companies and 11 million jobs — turns essential public infrastructure into profit extraction machines, often at lethal cost.

当一辆消防车在火灾现场无法展开云梯导致四人死亡时，其原因不仅仅是机械故障，更是一种商业模式。2025年6月26日晚，芝加哥“14号云梯车”的消防员赶往一栋公寓楼，一名纵火犯在两处楼梯间泼洒了汽油。当他们抵达时，云梯却无法升起。消防队员不得不将车辆完全熄火并重启。这一延误大约持续了一分钟。那晚有四人丧生——包括一名孕妇、她五岁的儿子，以及她的妹妹（她在坠亡前将自己的孩子从三楼窗户扔出逃生）。没有人告诉幸存的家属关于云梯故障的事，他们是从记者口中得知的。那辆故障的消防车是一个线索。顺藤摸瓜，你会发现这是私募股权行业如何将关键公共基础设施变成“利润榨取机器”的最清晰例证之一。这个规模达9.4万亿美元的行业，在幕后控制着约1.15万家美国公司和1100万个就业岗位，其代价往往是致命的。

The Business Model: Brilliant for Investors, Brutal for Everyone Else

商业模式：投资者的福音，他人的噩梦

Private equity is not a mystery. The mechanics are straightforward, the incentives are transparent, and the outcomes are predictable once you understand how the machine works. A private equity firm raises a fund — typically from pension funds, sovereign wealth funds, endowments, and wealthy individuals. It then acquires companies, usually through a leveraged buyout (LBO): a structure where 50 to 90 percent of the purchase price is financed by debt, and that debt is loaded onto the balance sheet of the acquired company, not the firm making the acquisition. The firm then charges the fund a management fee — historically 2 percent of assets annually — plus carried interest: a 20 percent cut of any profits, taxed at the long-term capital gains rate of 20 percent rather than the ordinary income rate of 37 percent. Critics have long called this a tax loophole. Congress has debated closing it for two decades and has not. US private equity AUM reached $3.128 trillion in 2024 alone, according to S&P Global. Total private markets AUM globally sits at approximately $15 trillion.

私募股权并非什么神秘事物。一旦你理解了这台机器的运作方式，其机制就变得直截了当，激励措施透明，结果也清晰可预测。一家私募股权公司会募集资金——通常来自养老基金、主权财富基金、捐赠基金和富有个体。随后，它通过杠杆收购（LBO）来收购公司：这是一种将收购价格的50%至90%通过债务融资的结构，且这些债务被计入被收购公司的资产负债表，而非收购方公司。接着，私募公司向基金收取管理费（通常为资产的2%），外加附带权益（carried interest）：即利润的20%作为分成，这部分收入按20%的长期资本利得税率征税，而非37%的普通所得税率。批评者长期以来称此为税收漏洞。国会对此争论了二十年，却始终未予堵塞。据标普全球统计，仅2024年，美国私募股权资产管理规模（AUM）就达到了3.128万亿美元。全球私募市场总资产管理规模约为15万亿美元。

The model works when applied to underperforming businesses that genuinely need restructuring. PE firms can bring operational discipline, growth capital, and strategic focus. That is the affirmative case, and it is real. The problem emerges when the model is applied to essential services with inelastic demand — industries where the customer has no choice but to pay, where quality degradation is hard to measure until catastrophe strikes, and where the typical PE timeline of 3-to-7 years before exit creates incentives to strip value rather than build it. The Senate Joint Economic Committee’s July 2024 report described this as a “buy, strip and flip” business model: PE firms load acquired companies with debt, cut costs aggressively, then resell at a profit — often at the direct expense of workers, communities, and the services those companies provide. Public companies acquired by PE are approximately ten times more likely to go bankrupt than a comparable control group subject to the same market forces, the report found.

当这种模式应用于确实需要重组的经营不善企业时，它是有效的。私募公司可以带来运营纪律、增长资本和战略重点。这是其积极的一面，也是客观存在的。但当这种模式应用于需求缺乏弹性的关键服务领域时，问题就出现了——在这些行业中，客户别无选择只能买单，质量下降在灾难发生前难以衡量，且私募股权通常3到7年的退出周期，促使他们倾向于榨取价值而非创造价值。参议院联合经济委员会2024年7月的报告将其描述为“买入、剥离、转手”的商业模式：私募公司将被收购公司背上沉重债务，激进削减成本，然后获利转售——这往往直接损害了员工、社区以及这些公司所提供的服务。报告发现，被私募股权收购的上市公司破产的可能性，大约是受相同市场力量影响的同类对照组的十倍。

The Fire Truck Racket: A Case Study in Manufactured Scarcity

消防车骗局：人为制造短缺的案例研究

The fire truck industry is the sharpest and most documented example of what PE consolidation does to essential services. Two decades ago, more than two dozen independent manufacturers competed to build America’s fire apparatus. Today, three companies control approximately 80 percent of the market: REV Group, Pierce Manufacturing (owned by Oshkosh Corporation), and Rosenbauer. This concentration was not an accident of market forces. It was engineered. REV Group is the centrepiece of the story. The company — owned by private equity firm American Industrial Partners — systematically acquired formerly independent manufacturers including E-One, Ferrara, KME, Ladder Tower, and Spartan. The old nameplates still exist as brand names. But behind them sits a single PE-backed conglomerate controlling a massive share of the supply chain for emergency vehicles that every American city depends on.

消防车行业是私募股权整合如何影响关键服务最尖锐、记录最详尽的案例。二十年前，有超过二十多家独立制造商竞争制造美国的消防设备。如今，三家公司控制了约80%的市场：REV Group、Pierce Manufacturing（隶属于Oshkosh Corporation）和Rosenbauer。这种集中并非市场力量的偶然，而是人为操纵的结果。REV Group是这个故事的核心。该公司由私募股权公司American Industrial Partners拥有，系统性地收购了包括E-One、Ferrara、KME、Ladder Tower和Spartan在内的多家曾经独立的制造商。旧的品牌名称依然存在，但其背后是一家由私募股权支持的单一企业集团，控制着每个美国城市所依赖的应急车辆供应链的巨大份额。

The result is a backlog that reads like a financial opportunity in earnings calls and a crisis in every fire station in the country. As of 2025, REV Group’s backlog stands at $4.5 billion. Wait times for a custom fire truck run to four years. Prices have doubled in a decade: a pumper truck now costs around $1 million; a ladder truck runs over $2 million. Profit margins in the industry have tripled — from the historic 4-to-5 percent range to over 13 percent. “Our $4.5 billion backlog is attractive among industrial manufacturers, is largely backed by municipal tax receipts, and offers significant value accretion opportunity, providing a pathway for growth and margin expansion over the next several years.” — Mark Skonieczny, CEO, REV Group, 2025 investor earnings call.

其结果是，在财报电话会议上，积压订单被视为财务机遇，而在全国各地的消防站，这却是一场危机。截至2025年，REV Group的积压订单额高达45亿美元。定制消防车的等待时间长达四年。价格在十年内翻了一番：一辆泵浦消防车现在的成本约为100万美元；一辆云梯车则超过200万美元。该行业的利润率翻了三倍——从历史上的4%至5%区间升至超过13%。“我们45亿美元的积压订单在工业制造商中极具吸引力，很大程度上由市政税收作为支撑，并提供了巨大的价值增值机会，为未来几年的增长和利润率扩张提供了路径。”——REV Group首席执行官Mark Skonieczny在2025年投资者财报电话会议上表示。

Note what Skonieczny is telling investors: the backlog is not a problem to be solved. It is an asset. The customers — fire departments serving American cities — are locked in because they have no alternative. Their orders, backed by tax receipts, are guaranteed revenue. The company’s incentive is to maintain the backlog, not eliminate it. The Senate heard this clearly. At a September 10, 2025 hearing, Senator Josh Hawley (R-MO) put it bluntly to the manufacturers: “This didn’t just happen to you accidentally. This is a business decision, isn’t it? You keep these backlogs like this. […] Another word for this would be a heist. This sounds to me like private equity came in; bought up all of these small companies; combined them; shut down their production; rolled up a huge backlog; massive profits; stiffed these guys; and now you’re making out like bandits.” — Sen. Josh Hawley, US Senate Subcommittee.

注意Skonieczny告诉投资者的话：积压订单不是需要解决的问题，而是一项资产。客户——服务于美国城市的消防部门——因为别无选择而被锁定。他们的订单由税收支持，是保证的收入。公司的激励机制是维持积压订单，而不是消除它。参议院对此听得一清二楚。在2025年9月10日的听证会上，参议员Josh Hawley（共和党，密苏里州）直言不讳地对制造商说：“这并非偶然发生。这是一个商业决策，对吧？你们保持这样的积压订单……换个词来说，这就是抢劫。在我看来，就像是私募股权进场，买下所有这些小公司，合并它们，关闭它们的生产线，堆积出巨大的订单积压，赚取巨额利润，坑害了这些人，而现在你们却像强盗一样发了大财。”——美国参议院小组委员会，参议员Josh Hawley。
