There is an American Star Trek mentality over the last fifty odd years - if you try hard enough it will work, your effort will reflect your output, and thus everyone will get out what they put in. The laws of physics say no, but with the right grit and determination the laws of physics will be overcome in half the time you thought it would take. It has been used on both sides of the political spectrum. As part of this Americanisation leadership has become a set of teachable values, you can do academic courses on it, you can learn to be a leader and inspire people to achieve way beyond their potential. It is balls.
Truth is leadership is innate, every toss pot who tries to demonstrate they have it instantly shows that they don't, but the world is full of leadership teams with strategies x, y and z, most of which involve bollock naked emporers and buzz words du jour. It is all over industry, society, education. Everywhere.
I will wager most people here can tell who they would follow when the whistle blows and who they would not. Being a leader is not necessarily a good thing- history is full of inspirational leaders inspiring atrocities, but in terms of sport, leadership is something innate and to be treasured. I don't buy that the private school system is a problem, societal problems I can get, but pro sports players no longer clean the boots of the pros on their way up, and like everyone else, they are told and treated as if they are special at an age when they are most vulnerable to believing it. Many sports have the same issues in the UK.
