I don't know about half of the crap I have read on this thread. Seriously. Leadership, management, what's the difference? Can you learn it from books, or from experience, or do you have to be born with it? Yadda, yadda, yadda.
Listen, most people at some point in their lives are placed in a position of leadership. Usually, they succeed. The point is that you make 12 year old Jimmy the Patrol Leader, and he will eventually get the campfire lit. When he grows up, he's going to be a foreman, a superintendent, a manager, a Senior VP, or something. Some rise to higher levels of responsibility than others, but all are leaders of some sort or another.
"Leadership" may not necessarily be an innate ability; it may be the combination of many different abilities -- some of which are personality driven and therefore "innate". Other of those abilities may be learned from study, and still others by experience.
But, I don't agree that an effective, high-level leader of great responsibility is born to be so. Otherwise, maybe we ought to reconsider our position on Monarchy vs. Democracy. At the very least, if leadership is an innate quality, it seems that it probably isn't that rare among the human species. Otherwise, we'd be stupid not to have a dictator instead of an elected government. After all, if leadership is rare, then it would be wise to appoint them for life.
In fact, dictators (like good leaders) seem to find a way into their positions without regard to rules, laws, or things like political mainstream views (remember that Hitler called himself a socialist and they bought it, even while he demonized communists, and still got himself elected in a country that called itself a republic - go figure).
A leader makes people move. That is not necessarily a good thing.
