The Three Things That Make Smart Men Go Broke, According to Billionaires
Two of the most respected investors in history often repeated a blunt warning about financial ruin. Charlie Munger summarized it in three words: “liquor, ladies, and leverage.” His longtime partner Warren Buffett repeated the line during a 2018 CNBC interview, noting that many intelligent people have destroyed their finances through those habits.
Buffett had already referenced the same idea in his 2010 shareholder letter for Berkshire Hathaway. Munger later said in 2023 that the company itself could have been worth twice as much if it had used leverage more aggressively.
Liquor: When Discipline Slips, So Do Decisions

Charlie Munger’s famous warning begins with liquor. Alcohol does not bankrupt an investor overnight, but it weakens judgment over time. Investing depends on clear thinking and disciplined decisions. Heavy drinking can interfere with both.
When judgment slips, risk is misjudged. Poor risk judgment leads to bad investment decisions. Markets respond quickly to those mistakes, and capital allocated poorly tends to disappear just as quickly.
Plenty of high earners confuse income with immunity. A seven-figure salary does not protect against poor habits. Over time, lifestyle creep turns into dependency, and dependency affects decisions. Buffett has often said investing is more about temperament than IQ, and liquor attacks temperament first.
Ladies: When Ego Becomes Expensive

The second L always draws attention. Munger phrased it as “ladies,” but Buffett later joked that the rhyme did some of the work. The deeper point is ego. Public divorces, private settlements, lavish lifestyles, and reputation management can drain fortunes faster than market downturns. History offers plenty of examples of executives and founders whose personal lives cost millions. Legal fees alone can rival startup budgets.
Munger experienced financial strain early in life. After divorcing his first wife in 1953, he was left with almost nothing. In the biography Damn Right: Behind the Scenes with Berkshire Hathaway Billionaire Charlie Munger, his daughter Molly recalled that he lost everything in the divorce, including the family home. He rebuilt his wealth slowly, and he did it without borrowing heavily.
Leverage: The One That Actually Destroys Empires
Leverage is the real killer. In the same 2018 CNBC interview, he explained that while some people become rich using borrowed money, it is also a reliable way to become very poor. In his 2010 shareholder letter, he wrote that history shows leverage often produces zeros, even when used by very smart people.
Leverage magnifies outcomes. A 10 percent gain can double equity when debt is involved, and a 10 percent loss can wipe it out. Debt demands repayment on schedule, even when markets disagree.
Munger acknowledged in a 2023 CNBC special with Becky Quick that Berkshire Hathaway could easily be worth twice its size if it had used more leverage. He said the extra risk would have been small for them personally. They chose restraint anyway. He explained that losing three-quarters of their own money would still have left them wealthy, but that was not true for every shareholder who trusted them.
Recent history reinforces the point. During the 2021 crypto surge, firms such as Three Arrows Capital borrowed heavily to amplify bets. When prices collapsed in 2022, the leverage turned volatility into insolvency. Billions evaporated, and intelligence offered no protection against margin calls.
Leverage feels efficient, promises speed, and removes patience from the equation. Buffett has built wealth by compounding steadily for decades. He has never needed borrowed money to prove a point.
