spot on. I didn’t do the math too well. The first boomers (born in 46) are no older than 66 years old.
I never actually knew all the folks you mention, I’m just thinking of all my eldest brother’s (RIP) hippie friends who were pretty much as you describe. But they were all boomers. Born in 1950 or so.
Without question millions of the boomers who were old enough, participated in the 1960s, they just weren’t the true generation of the 60s.
In 1960 the Beatniks were already well established and were becoming the hippies, the oldest boomer on the planet was only 14 years old. By 1969 the oldest boomer was 23 and the youngest 5 years old, yet many people have them running the Congress, the Senate, the Presidency, the 1960s and the Vietnam War, the Supreme Court, passing all of the bad legislation, running the University systems, running television and the media, movies, and on and on.
The boomers didn’t really start asserting power until the 1980s. By 1990, boomers were the adults ranging in age from 26 to 44 and they were the Reagan generation, 1984 was the first election in which all boomers were old enough to vote in a presidential election, they were also the last great ‘military generation’ with almost 9&1/2 million veterans.
