Em economia, a senhora gorda nunca canta

Via Paulo Peres cheguei a este texto "Truly Great Companies Add More Than They Extract".
.
O artigo critica a metodologia de Jim Collins porque:

"For “Good to Great,” his most successful book, published in 2001, Mr. Collins selected 11 companies as truly elite performers. They included Circuit City (now bankrupt and defunct); Fannie Mae (taken over by the government in 2008 after huge mortgage losses); Pitney Bowes, whose stock has progressively tanked over the last decade;
...
In “Great by Choice,” published in 2011, Mr. Collins and a co-author, Morten T. Hansen, call out seven companies for “spectacular” results – outperforming the overall stock market and their industry competitors by at least 10 times over a 15-year period. They also set up comparisons with companies in the same industries that performed markedly less well.
.
The most striking comparison involves Microsoft, which Mr. Collins and Mr. Hansen identify as a great performer, and Apple, which they cite as the comparative laggard. Yes, you read that right. Here’s why: the 15-year period the authors happened to examine was 1987 to 2002.
.
How could so much research miss the mark by so far?"

Depois, o autor procura descrever uma metodologia diferente para distinguir as empresas realmente fantásticas.
.
E eu, começo logo a imaginar, daqui a 10 anos, alguém a comparar o desempenho da (em 2023 colocar aqui o nome de empresa bem sucedida de então) com o desempenho da outrora famosa Apple.
.
Já vi este filme nos anos 90 do século passado, quando Tom Peters foi criticado porque as empresas do livro "A Paixão pela Excelência" ou estavam mal ou tinham falido.
.
As empresas são seres vivos e, como tal, o mais natural é terem um tempo para crescerem, um tempo para dominarem e um tempo para morrerem ou para se arrastarem com ou sem dignidade. O que não acho natural é pensar que as empresas têm de durar para sempre, o que não acho natural é não admitir que tudo é transiente e que aquilo que é verdade hoje, amanhã é mentira, porque o mundo muda.

E volto a Beinhocker e aquela citação saborosa complementada pelo facto da senhora gorda, em economia, nunca cantar, porque ela canta no fim e em economia nunca há fim.

E recordo a história que recentemente recordei ao ler Fooled by Randomness:

"Croesus, King of Lydia, was considered the richest man of his time. To this day Romance languages use the expression "rich as Croesus" to describe a person of excessive wealth. He was said to be visited by Solon, the Greek legislator known for his dignity, reserve, upright morals, humility, frugality, wisdom, intelligence, and courage. However, Solon did not display the smallest surprise at the wealth and splendor surrounding his host, nor the tiniest admiration for their owner. Croesus was so irked by the manifest lack of impression on the part of this illustrious visitor that he attempted to extract from him some acknowledgment. He asked him if he had known a happier man than him. Solon cited the life of a man who led a noble life and died while in battle. Prodded for more, he gave similar examples of heroic but terminated lives, until Croesus, irate, asked him pointblank if he was not to be considered the happiest man at all. Solon answered: "The observation of the numerous misfortunes that attend all conditions forbids us to grow insolent upon our present enjoyments, or to admire a man’s happiness that may yet, in course of time, suffer change. For the uncertain future has yet to come, with all variety of future; and him only to whom the divinity has continued happiness until the end we may call happy."
