“There is nothing so disturbing to one's well-being and judgment as to see a friend get rich.”Charles P. Kindleberger · Manias, Panics, and Crashes: A History of Financial Crises · 1978 · Manias, Panics, and Crashes: A History of Financial Crises, partea I, cap. despre „Anatomia unei crize tipice"
A bubble spreads through the neighbor's envy, not through numbers: you buy late precisely because others visibly profit.
Kindleberger, who studied centuries of financial crises, argues that every bubble follows a pattern: displacement, euphoria, then panic. The mechanism feeding the euphoria phase is not analysis but envy and the fear of missing an opportunity others visibly enjoy. When a neighbor or colleague is visibly winning, rational judgment gives way to the pressure not to be left behind, and late entrants inflate the price until it breaks. He points to the 1920s land and stock manias, when ordinary people entered markets they did not understand simply because everyone around them was making money.
Kindleberger points to a simple test for the moment a decision stops being yours. Ask yourself: would I still get in if nobody around me were making money? If the answer is no, you are not buying an asset, you are buying social comfort. The discomfort of falling behind becomes the price you pay, on top of the thing's real value. That is why bubbles break precisely when the last entrants arrive, those who can no longer bear the comparison. Think of a group of friends who all change cars within a year. One buys not for the car, but to avoid being the only one with the old one. Next, we look at why the neighbor matters more than national statistics.
Why it matters Any wave of enthusiasm around an industry or a price travels through exactly this channel: comparison with those close to us, not with statistics. The idea helps you spot the moment when your decision is actually someone else's, copied.
