$460 billion. That is how much market capitalization General Electric lost during the sixteen years Jeffrey Immelt served as its chief executive — a destruction of value so total that GE was eventually removed from the Dow Jones Industrial Average it had anchored since 1907.

Immelt inherited GE from Jack Welch in 2001, days before September 11th. He stepped into the role of a company that was, by every conventional measure, the most admired corporation in the world. His instinct — reasonable, human, broadly praised at the time — was to rebuild trust. He positioned himself as the antithesis of the ruthless Welch era. He emphasized integrity. He communicated optimism. He made acquisitions that signaled confidence. When GE Capital, the financial engine that generated roughly half of GE's earnings, began accumulating systemic risk through the 2000s, Immelt received internal warnings. The signals were curable. He managed the perception of stability rather than the underlying structural fragility. He was, by all public accounts, a man trying to do the right thing for a company he genuinely believed in.

Machiavelli wrote the precise description of what happened next in 1513 — 504 years before Immelt's tenure ended. The chapter reads: 'Knowing afar off the evils that are brewing, they are easily cured. But when, for want of such knowledge, they are allowed to grow so that every one can recognise them, there is no longer any remedy to be found.' He uses a medical analogy that has not aged: hectic fever, easy to cure when unrecognized, incurable once diagnosed by everyone in the room. GE Capital's exposure to the 2008 financial crisis was not hidden from those who looked. The insurance liabilities that would later require a $6.2 billion charge were not discovered after the fact — they were known, managed around, and disclosed to shareholders in forms designed to project confidence rather than alarm. By the time every analyst could see the problem, GE had no remedy that did not also constitute an admission of prior concealment.

GE's stock lost more than 70 percent of its value between 2000 and 2018. In 2018, the company took a $23 billion goodwill impairment charge on the power division — one of Immelt's signature acquisitions. GE Capital, which had been the company's growth engine, became its albatross. The company that had defined American industrial supremacy for a century was broken into pieces.

Immelt was praised throughout his tenure for his communications style, his values-based leadership, and his long-term orientation. He was a man who made a profession of goodness. He was not hated. He was not cruel. He was not rapacious. He managed perception in fair weather and discovered, when the storm arrived, that he had built no dams.

You already know what you are managing around.

$985 million in losses in a single fiscal year, generated not by market collapse or external shock, but by a chief executive who refused to test his convictions before betting the company on them. Ron Johnson had the most credible retail biography of his generation. He had built the Apple Store concept from nothing — a format so successful it became the highest-revenue-per-square-foot retail operation in history. When William Ackman's Pershing Square Capital brought him to J.C. Penney in 2011, the logic was irresistible: the man who reinvented how Apple sold products could reinvent how a department store sold clothes.

Johnson arrived with a radical diagnosis and a total solution. J.C. Penney's addiction to promotional pricing — the artificial markups, the relentless coupons, the manufactured urgency of sale events — was the disease. He would cure it with honesty: everyday low prices, no gimmicks, a store redesigned as a collection of branded shops-within-shops. His confidence was not arrogance. It was the earned certainty of someone who had been right before about something no one else believed.

The error was not the strategy. The error was the execution of reform without building the foundation first. Machiavelli described this mechanism in 1513 — 498 years before Johnson's appointment: 'There is nothing more difficult to carry out, nor more doubtful of success, nor more dangerous to handle, than to initiate a new order of things. For the reformer has enemies in all those who profit by the old order, and only lukewarm defenders in all those who would profit by the new order.' He then identifies the structural condition that determines survival: armed reformers succeed, unarmed ones fail. Johnson had no army. He had a board, an activist investor, and a theory. He did not pilot his pricing model in a subset of stores before rolling it out nationally. He told shareholders directly that testing was for people who lacked conviction. J.C. Penney's core customer — who had been trained for decades to feel the pleasure of the coupon, the satisfaction of the deal — stopped coming. Foot traffic collapsed 10 percent in the first year. Same-store sales fell 25 percent. The company burned through $1 billion in cash in 17 months.

Johnson was removed in April 2013, seventeen months after taking the role. The company spent the next six years attempting to recover customers it had lost in a single quarter. It filed for bankruptcy in 2020.

The principle had been available for five centuries. The reformer who cannot force adoption must first build the constituency that will protect the reform — or test quietly until the evidence is irrefutable. Johnson did neither. He announced a new order of things to people who profited from the old one, and discovered that lukewarm defenders do not hold the line.

Your next transformation is already being planned. The question is whether you are building the army before the announcement.
