Kurt Vonnegut in “God Bless You Mr. Rosewater” (1965) accounts for libertarian achievements in the degenerate society during the Golden Age of Rome:
Having said that, he went into the Senate Chamber to deliver his fairly famous speech on the Golden Age of Rome, in which he said, in part:
I should like to speak of the Emperor Octavian, of Caesar Augustus, as he came to be known. This great humanitarian, and he was a humanitarian in the profoundest sense of the word, took command of the Roman Empire in a degenerate period strikingly like our own. Harlotry, divorce, alcoholism, liberalism, homosexuality, pornography, abortion, venality, murder, labor racketeering, juvenile delinquency, cowardice, atheism, extortion, slander, and theft were the height of fashion. Rome was a paradise for gangsters, perverts, and the lazy working man, just as America is now. As in America now, forces of law and order were openly attacked by mobs, children were disobedient, had no respect for their parents or their country, and no decent woman was safe on any street, even at high noon! And cunning, sharp-trading, bribing foreigners were in the ascendency everywhere. And ground under the heels of the big city money-changers were the honest farmers, the backbone of the Roman Army and the Roman soul.
What could be done? Well, there were soft-headed liberals then as there are bubble-headed liberals now, and they said what liberals always say after they have led a great nation to such a lawless, self indulgent, polyglot condition: “Things have never been better! Look at all the freedom! Look at all the equality! Look how sexual hypocrisy has been driven from the scene! Oh boy! People used to get all knotted up inside when they thought about rape or fornication. Now they can do both with glee!”
And what did the terrible, black-spirited, non-fun-loving conservatives of those happy days have to say? Well, there weren’t many of them left. They were dying off in ridiculed old age. And their children had been turned against them by the liberals, by the purveyors of synthetic sunshine and moonshine, by the something for-nothing political strip-teasers, by the people who loved everybody, including the barbarians, by people who loved the barbarians so much they wanted to open all the gates, have all the soldiers lay their weapons down, and let the barbarians come in!
