How is the balance between spiritedness and subservience to "manners" different between Jiro's world and ours?
In Jiro's world, selfless, large-hearted leaders and teachers (from parents upward) understand that unscrupulous, evil-minded, small-hearted people are prevalent in life and that their presence sets up unjust, harmful and even destructive obstacles or even impassable barriers to good, desirable and appropriate end results. In Jiro's world, the selfless master teachers manipulate events so that students, like Jiro, encounter such obstacles and barriers in a safe environment (like in their apprenticeships) and are forced by these to develop their resources for dealing with such things. Furthermore they learn through this benign manipulation to recognize these harmful or destructive obstacles and barriers so that they will know them when they come across selfish manipulations in their adult lives.
In our world, the social belief is that all mankind is essentially good and that evil-minded and small-hearted manipulations are an anomaly and the unexpected--not the expected. (Reality screams around us that this is not so--perhaps blindness to the existence of such manipulators has made the presence of selfish manipulations spread and grow like yeast in bread dough.) In our world we are not prepared to recognize selfish harmful manipulations as Jiro is taught to do in his world.
