Many of the historical "Golden Ages" were... golden... only for the elites, whose high levels of consumption were based on low real wages and falling consumption levels of the great majority...

The "golden age" is the exception, normal history is "grey".

This is truly the age of gold,
since only gold wins and gold reigns.

So there's no question about it: by the mid-fifties, America was definitely in a Golden Era, an era of excitement and opportunity for all citizens, regardless of race or creed or color, unless the person happened to be black. Then there was a problem.

That there have been in all ages and in all countries, in every quarter of the habitable globe, especially among those nations laying the greatest claim to civilization and enlightenment, classes of people who have been deprived of equal privileges, political, religious and social, cannot be denied, and that this deprivation on the part of the ruling classes is cruel and unjust, is also equally true. Such classes have even been looked upon as inferior to their oppressors, and have ever been mainly the domestics and menials of society, doing the low offices and drudgery of those among whom they lived, moving about and existing by mere sufferance, having no rights nor privileges but those conceded by the common consent of their political superiors. These are historical facts that cannot be controverted.

All eras of history are an equal distance from eternity.

In the history of the human race, those periods which later appeared as great have been the periods when the men and the women belonging to them had transcended the differences that divided them and had recognized in their membership in the human race a common bond.

The history of the world is the history of a privileged few.

The ruling ideas of each age have ever been the ideas of its ruling class.

The era of the masses, which follows the age of the republics, excites the feelings and dazzles the eyes. But even though the vision of this era denotes genuine freedom of the masses and their happy emancipation from the bonds of external authoritarian structures, it warns also of the dangers of a period of chaos and demagoguery, and the threat of a return to the authority of the individual, the sect and party, instead of the authority of the people. Theoretically, this is genuine democracy but, realistically, the strong always rules. That is, the stronger party in the society is the one that rules.

No period of history has ever been great or ever can be that does not act on some sort of high, idealistic motives, and idealism in our time has been shoved aside, and we are paying the penalty for it.

All epochs exhibit the same vices, but not all show the same virtues. In every age there are hovels, but only in some are there palaces.

The residents had eliminated both past and future, and for all their activity, they existed in a civilized and eventless world.

Ours is a golden age of minorities. At no time in the past have dissident minorities felt so much at home and had so much room to throw their weight around. They speak and act as if they were "the people," and what they abominate most is the dissent of the majority.
