True, there is much Lamarckian evolution going on - employees of one company or industry regularly learn about what the current best practices (or latest fad) are in their industry or in other industries. Plus employees engage in lateral meme transfer as they move on to different companies, and sometimes to different industries.
But if the literature of business history is littered with the stories of well-run companies that couldn't cope with a changing industry, changing marketplace, changing technologies - as well as stories of small companies that defied the odds to make it big, and in a few cases transform an industry.
Failure in business is the rule. This is true for small companies, but also for larger companies over longer timescales. The marketplace is a chaotic beast, despite the efforts of the best & brightest to navigate their companies thru the years.
And if the economy was a designed entity like you seem to believe it is, then Communism, or some other kind of technocratic or corporate-fascist dictatorship, would be a much more efficient system for maximizing the wealth of nations than free market capitalism.
What "economy", describe what you are talking about. You are shotgunning terms and claims left and right.
