Americans have so far put up with inequality because they felt they could change their status. They didn't mind others being rich, as long as they had a path to move up as well. The American Dream is all about social mobility in a sense - the idea that anyone can make it.
Change means movement. Movement means friction. Only in the frictionless vacuum of a nonexistent abstract world can movement or change occur without that abrasive friction of conflict.
It is not necessary to change. Survival is not mandatory.
The most useless are those who never change through the years.
Become a student of change. It is the only thing that will remain constant.
Those who visit foreign nations, but associate only with their own country-men, change their climate, but not their customs. They see new meridians, but the same men and with heads as empty as their pockets, return home with traveled bodies, but untravelled minds.
It is proof of a base and low mind for one to wish to think with the masses or majority, merely because the majority is the majority. Truth does not change because it is, or is not, believed by a majority of the people.
Let the great world spin for ever down the ringing grooves of change.
Habits change into character.
Every daring attempt to make a great change in existing conditions, every lofty vision of new possibilities for the human race, has been labeled Utopian.
