I agree with your point that it is incumbent upon every individual to continually improve themselves. However, I like point out whenever this sentiment is brought up (including by myself) that while individuals must continuously improve, it does not necessarily follow that organizations will improve. Even if those very organizations are crammed with lots of those continuously-improving individuals. Especially large, monopolistic or duopolistic organizations with a lot of staying power over long periods of time.
