My objection, or I guess social critique, is that we have a lot of undue reverence for decision-making. It's important yes, and can have a big impact, but it's just a skill, not fundamentally different from other skills, and isn't especially more difficult than most.
The Little Dutch Boy had a huge impact too, because of the leverage of the situation he found himself in, but we don't seem to imbue sticking your thumb in things with any special reverence.
The brand of leadership which gains actual reverence in society seems to be top performers. And top performance in any role is revered. Brain surgeons, athletes, "rockstar programmers", investment bankers, etc. all possess a certain 'aura' about them that makes people idolize them, perhaps disproportionately or unfairly in some cases. But I would say your "Steve Ballmer" brand of CEO does not get much reverence in society whatsoever.
Leadership is the ability to make decisions on behalf of the group under you that are good. It's seen as being altruistic because it can enhance, or detract from the quality of work, and the quality of life of everybody beneath you. The effect of good decision making is multiplicative based on how great the scope of your 'leadership' is. A good decision maker in charge of 100,000 people will therefore bring a lot more productivity and positivity to society than a good decision maker in charge of only 100 people.
Moving forward by replacing 'leadership' with the term 'decision making' - which is really what it is - there are a lot of individuals who have consistent history of good decision making. These individuals exemplify good decision making far too often for it to be a function of luck or random chance. Of course, there are definitely some people who got lucky and were mistakenly labeled as 'good decision makers' (lest we forget November 2016). I'd also say that because we don't live in anything remotely close to a meritocracy, some people achieve leadership and management only because they come from a position of privilege in society. Nevertheless, the concept of good decision makers bearing great importance in society should not be dismissed, because historically the human race has excelled, or completely grinded to a halt based on how, and who we let make decisions.
