life continues to change

This is another excerpt from the book I'm reading

Do not underestimate the rôle of these sentiments in the life of man or nation. We do not live by bread alone. True, existence is not possible without opportunity to satisfy our physical needs. But the gratification of these by no means constitutes all of life. Our present system of civilization has, by disinheriting millions, made the belly the center of the universe, so to speak. But in a sensible society, with plenty for all, the matter of mere existence, the security of a livelihood would be considered self-evident and free as the air is for all. The feelings of human sympathy, of justice and right would have a chance to develop, to be satisfied, to broaden and grow. Even to-day the sense of justice and fair play is still alive in the heart of man, in spite of centuries of repression and perversion. It has not been exterminated, it cannot be exterminated because it is inborn, innate in man, an instinct as strong as that of self-preservation, and just as vital to our happiness. For not all the misery we have in the world co-day comes from the lack of material welfare. Man can better stand starvation than the consciousness of injustice. The consciousness that you are treated unjustly will rouse you to protest and rebellion just as quickly as hunger, perhaps even quicker. Hunger may be the immediate cause of every rebellion or uprising, but beneath it is the slumbering antagonism and hatred of the masses against those at whose hands they are suffering injustice and wrong. The truth is that right and justice play a far more important rôle in our lives than most people are aware of. Those who would deny this know as little of human nature as of history. In every-day life you constantly see people grow indignant at what they consider to be an injustice. "That isn't right," is the instinctive protest of man when he feels wrong done. Of course, every one's conception of wrong and right depends on his traditions, environment and bringing up. But whatever his conception, his natural impulse is to resent what he thinks wrong and unjust.

Historically the same holds true. More rebellions and wars have been fought for ideas of right and wrong than because of material reasons. Marxists may object that our views of right and wrong are themselves formed by economic conditions, but that in no way alters the fact that the sense of justice and right has at all times inspired people to heroism and self-sacrifice in behalf of ideals.

I have put in bold type what is important here...as life changes, as it will always do continually, it is easy to dismiss this bold faced type.  The difference? Since this script was originally written, humans have discovered a way to get messages across to the masses via TV, radio, and now the internet.  It is much easier for the government to send out messages of injustice to fool you into believing in a war, that in all actuality is about the material benefit to the government itself.
