I think leadership, as Old Dad defines is a cultural thing. You had some visionary entrepeneurs who built companies in the beginning of the Internet boom. But since all those companies produced so many instant millionaires in the boom, CEOs of regular corporations demanded higher salaries and incentives and you got outrageous pay for management and a change in attitude towards shareholder profit rather than corporate health.
I think that having a healthy, cohesive corporate organism was a flash in the pan idea in the 80s, after the Japanese management style invaded the bookshelves.
