In fact, I think this doctrine is the basis of the so-called American manners.
All men are deemed socially equal, whether as friend and friend, as President and citizen, as employer and employee, as master and servant, or as parent and child.

Their relationship may be such that one is entitled to demand, and the other to render, certain acts of obedience, and a certain amount of respect, but outside that they are on the same level.

This is doubtless a rebellion against all the social ideas and prejudices of the old world, but it is perhaps only what might be looked for in a new country, full of robust and ambitious manhood, disdainful of all traditions which in the least savor of monarchy or hierarchy, and eager to blaze as new a path for itself in the social as it has succeeded in accomplishing in the political world.

Combined with this is the American characteristic of saving time.

Time is precious to all of us, but to Americans it is particularly so.
