I've taken awhile to ponder that statement and consider it from multiple angles. It is wrong. The '60s was nothing other than the Boomers coming into their own. It was Boomers who turned the Beatles demigods. It was Boomers who were buying the Mopar muscle cars, the Mustangs, the GTOs, the Trans Ams, and Firebirds in the '60s. It was Boomers who were either being drafted or protesting the war, and sometimes both. It was Boomers who were into psychodelia, drugs, long hair, bell bottoms, and all the music from the mid-'60 to the mid-'70s. These things created the culture of that decade, apart from its politics.
Those who came of age in the '60s will recall the opening lines of A Tale of two Cities: "It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of Life, it was the season of Darkness, it was the spring of hope, it was the winter of despair, we had everything before us, we had nothing before us, we were all going direct to Heaven, we were all going direct the other way". How true.
If you think children ran things then go ahead.
In 1965 boomers ranged in age from 1 year old to an old man teenager of 19 years old, I don’t know how many teens and 8 year olds could afford those expensive cars.
