A fixação no equilíbrio e os outros

Ontem à noite fui pela enésima vez à procura da história sobre o nascimento da fama de uma marca de botas suíça, na Bíblia escrita pelo homem que mudou a minha vida, "Management: Tasks, Responsibilities, Practices" de Peter Drucker. E pela enésima vez falhei, não a consegui encontrar. Então, surgiu a dúvida, terá sido no primeiro livro que li de Drucker, "Inovação e Gestão"?  Também não... mas ficou-me este trecho:

"Entrepreneurship rests on a theory of economy and society. The theory sees change as normal and indeed as healthy. And it sees the major task in society - and especially in the economy - as doing something different rather than doing better what is already being done. This is basically what Say, two hundred years ago, meant when he coined the term entrepreneur. It was intended as
a manifesto and as a declaration of dissent: the entrepreneur upsets and disorganizes. As Joseph Schumpeter formulated it, his task is “creative destruclion.”
.
Say was an admirer of Adam Smith. He translated Smith’s Wealth of Nations (1776) into French and tirelessly propagated throughout his life Smith’s ideas and policies. But his own contribution to economic thought, the concept of the entrepreneur and of entrepreneurship, is independent of classical economics and indeed incompatible with it. Classical economics optimizes what already exists, as does mainstream economic theory to this day, including the Keynesians, the Friedmanites, and the Supply-siders. It focuses on getting the most out of existing resources and aims at establishing equilibrium. It cannot handle the entrepreneur but consigns him to the shadow realm of “external forces,” together with climate and weather, government and politics, pestilence and war, but also technology. The traditional economist, regardless of school or “ism,” does not deny, of course, that these external forces exist or that they matter. But they are not part of his world, not accounted for in his model, his equations, or his predictions."

Realmente, quando ouvimos os membros da tríade... e a sua fixação no equilíbrio... assim, muita coisa fica esclarecida.

BTW, a história era a de dois irmãos suíços que tinham uma fábrica de botas. Entretanto, um dos irmãos foi combater ao lado dos franceses, durante a I Guerra Mundial. Das trincheiras mandava cartas para o irmão, como utilizador, sugerindo melhorias no produto, sugerindo melhorias no output, para melhorar os outcomes.
