No boomer was voting in the "mid-1960s" and the first election in which all boomers were old enough to vote for president, was in 1984.
Not accurate by a long shot. I'm a baby boomer (born in 1953), and the first presidential election I participated in was in 1972.
A few of the young men who came of age during the 1960s enlisted or were drafted and went to Vietnam. A few of the young sons of business and government leaders tried to dodge the draft, while most working class young men were willing to fight. In 1969 or so, noticeable numbers of younger men of all classes and career directions feared the draft and started finding ways to dodge it.
The voting age was lowered to 18 in 1971. In the early 1970s, more than half of us Baby Boomers were allowed to vote.
Around 1968, some of the neighborhood teenagers started smoking pot, especially in tourist areas, and later trying other drugs.
Around 1969, some of the girls my age in tourist areas started using foul language in public, and the first few relatives in the extended family were pregnant outside of marriage. Girls in junior high schools started dressing very promiscuously in the late 1960s or early 1970s, depending on what part of the country they were in (jeans, very short miniskirts, halter tops without bras, “hiphuggers” no different from the contemporary “low riders,” etc.).
Boys spoke more commonly and crudely about sex with girls and less about dates, “steadies,” girlfriends, marriage, etc.
By the late 1970s, quite a few manufacturers looked for cheaper labor in foreign countries. Contrary to myths, most manufacturing jobs didn’t pay much during the 1970s (one example, $3.80 and hour for new laborers in shops working with steel $7-something starting wage for experienced custom machinists). But one or two southern states were a little cheaper, and countries like Mexico far cheaper than that. During the 1980s, many more followed, and so on.
Remaining manufacturing shops generally rejected men and tried to hire more women (pressure from business, academia, all). Rates of repetition injuries in women in those jobs skyrocketed, and those operations were sent to other countries. By then, fatherhood in the context of traditional families was effectively outlawed for working class men, while the serial monogamy we see exhibited by managers and moguls was more legalized (no-fault divorce and associated big government social offices against implemented).
So would "later '60s" sound better to you?
The last of it is considered 1964, so 1964+18=1982 not 1984.
I don't remember many discounts for seniors before the mid '90s.
