They got more conservative as they got older. All those hippie kids who protested Vietnam and experimented with drugs and sex ended up voting for Reagan.
People seem to have this view that everyone in the '60s was a hippie but that's just not true. Time Magazine put the number around 300,000. In a country of 200 million, that's only 0.15% of the population. They were a counterculture not mainstream culture. The vast majority of kids did not become hippies, and many actively hated the hippies.
Uh huh. Here's some historical views of the 'yoot'.
“[Young people] are high-minded because they have not yet been humbled by life, nor have they experienced the force of circumstances... They think they know everything, and are always quite sure about it.”
Rhetoric, Aristotle - 4th Century BC
“The beardless youth… does not foresee what is useful, squandering his money.”
Horace - 1st Century BC
Our sires' age was worse than our grandsires'. We, their sons, are more worthless than they; so in our turn we shall give the world a progeny yet more corrupt.
Book III of Odes, Horace - circa 20 BC
In all things I yearn for the past. Modern fashions seem to keep on growing more and more debased. I find that even among the splendid pieces of furniture built by our master cabinetmakers, those in the old forms are the most pleasing. And as for writing letters, surviving scraps from the past reveal how superb the phrasing used to be. The ordinary spoken language has also steadily coarsened. People used to say "raise the carriage shafts" or "trim the lamp wick," but people today say "raise it" or "trim it." When they should say, "Let the men of the palace staff stand forth!" they say, "Torches! Let's have some light!" Instead of calling the place where the lectures on the Sutra of the Golden Light are delivered before the emperor "the Hall of the Imperial Lecture," they shorten it to "the Lecture Hall," a deplorable corruption, an old gentleman complained.

Youth were never more sawcie, yea never more savagely saucie . . . the ancient are scorned, the honourable are contemned, the magistrate is not dreaded.
The Wise-Man's Forecast against the Evill Time, Thomas Barnes - 1624
... I find by sad Experience how the Towns and Streets are filled with lewd wicked Children, and many Children as they have played about the Streets have been heard to curse and swear and call one another Nick-names, and it would grieve ones Heart to hear what bawdy and filthy Communications proceeds from the Mouths of such...
A Little Book for Children and Youth, Robert Russel - 1695
“Whither are the manly vigour and athletic appearance of our forefathers flown? Can these be their legitimate heirs? Surely, no; a race of effeminate, self-admiring, emaciated fribbles can never have descended in a direct line from the heroes of Potiers and Agincourt...”
Letter in Town and Country magazine republished in Paris Fashion: A Cultural History - 1771
The total neglect of this art [speaking] has been productive of the worst consequences...in the conduct of all affairs ecclesiastical and civil, in church, in parliament, courts of justice...the wretched state of elocution is apparent to persons of any discernment and taste… if something is not done to stop this growing evil …English is likely to become a mere jargon, which every one may pronounce as he pleases.
A General Dictionary of the English Language, Thomas Sheridan - 1780
The free access which many young people have to romances, novels, and plays has poisoned the mind and corrupted the morals of many a promising youth; and prevented others from improving their minds in useful knowledge. Parents take care to feed their children with wholesome diet; and yet how unconcerned about the provision for the mind, whether they are furnished with salutary food, or with trash, chaff, or poison?
Memoirs of the Bloomsgrove Family, Reverend Enos Hitchcock - 1790
We remarked with pain that the indecent foreign dance called the Waltz was introduced (we believe for the first time) at the English court on Friday last … it is quite sufficient to cast one's eyes on the voluptuous intertwining of the limbs and close compressor on the bodies in their dance, to see that it is indeed far removed from the modest reserve which has hitherto been considered distinctive of English females. So long as this obscene display was confined to prostitutes and adulteresses, we did not think it deserving of notice; but now that it is attempted to be forced on the respectable classes of society by the civil examples of their superiors, we feel it a duty to warn every parent against exposing his daughter to so fatal a contagion.
The Times of London - Summer, 1816
...a fearful multitude of untutored savages... [boys] with dogs at their heels and other evidence of dissolute habits...[girls who] drive coal-carts, ride astride upon horses, drink, swear, fight, smoke, whistle, and care for nobody...the morals of children are tenfold worse than formerly.
Anthony Ashley Cooper, the 7th Earl of Shaftesbury, Speech to the House of Commons - February 28, 1843
... see the simpering little beau of ten gallanting home the little coquette of eight, each so full of self-conceit and admiration of their own dear self, as to have but little to spare for any one else... and confess that the sight is both ridiculous and distressing... the sweet simplicity and artlessness of childhood, which renders a true child so interesting, are gone (like the bloom of the peach rudely nipped off) never to return.
"Children And Children's Parties", published in The Mothers' Journal and Family Visitant, S.B.S. - 1853
Household luxuries, school-room steam-press systems, and, above all, the mad spirit of the times, have not come to us without a loss more than proportionate...[a young man] rushes headlong, with an impetuosity which strikes fire from the sharp flints under his tread...Occasionally, one of this class...amasses an estate, but at the expense of his peace, and often of his health. The lunatic asylum or the premature grave too frequently winds up his career...We expect each succeeding generation will grow "beautifully less."
“Degeneracy of Stature”, The National Era, Thrace Talmon - December 18, 1856
A pernicious excitement to learn and play chess has spread all over the country, and numerous clubs for practicing this game have been formed in cities and villages...chess is a mere amusement of a very inferior character, which robs the mind of valuable time that might be devoted to nobler acquirements, while it affords no benefit whatever to the body. Chess has acquired a high reputation as being a means to discipline the mind, but persons engaged in sedentary occupations should never practice this cheerless game; they require out-door exercises--not this sort of mental gladiatorship.
Scientific American - July, 1858
You have 4 people, 3 liberals and 1 conservative, graduating from high school at 18, 75% are liberal. When they are in their late 30s, one of the liberals dies, so 66% are liberals. Then at age 50 another liberal dies, so the group is 50% liberal. One year after retirement (65) the last liberal dies and now the entire cohort is conservative. Without looking at the size of the population, one would think that the group of 4 slowly became more conservative over time.
Death, not persuasion, causes the political leaning of the population to shift as they get older. It is the very concerns of those that are liberal which also lead to their earlier deaths. If you are less likely to die from something that can be fixed with politics, you are more likely to be conservative and not want to rock the boat.
It turns out that the media jumped all over things like Hippies and anti-war protests. In reality, the average person was just as conservative then as they were 10 - 20 years ago.
