It's still the same thing: Taking credit for other people's work and claiming it as your own. It's also probably a good reason to democratize decision making when there's a lot on the line. Because, ultimately, everyone suffers from the bad decisions that people in power make.
Even if assuming the ‘leverage’ is of overriding importance, Isn’t it fairly obvious that in this example the general could also make the wrong decision which will also leverage the work of millions, missile builders and so on, to a very negative outcome?
If that occurs, do the millions of folks who worked directly on some aspect bear collective responsibility? And the general’s decision then becomes inconsequential in the mass of millions of other decisions?
Your line of reasoning leads to an absurd conclusion in which no one’s decisions can have a disproportionate impact.
In the most extreme case, say some military general’s correct judgement to avoid launching a nuclear missile during a false alert, may be worth more than everyone else’s combined. i.e their ‘good judgement’ during a critical few seconds would be worth 8 billion times more than the average.
