There's hardly anyone left who remembers the roaring 20's. Even the youngest WWII vets still alive are close to 90.
I think she means not somebody literally old enough to remember it but just closer to it historically.
That being said, my grandmothers were a little too old for the roaring 20s , but even if they hadn’t been, they probably wouldn’t have partaken. Though one of them smoked cigarettes they were extreme teetotallers and disapproved of Coca-Cola because they could remember when it had real cocaine in I guess. One of them died a year before I was born but I know these things from what others told me.
It’s hard to picture a recent sea change of this type as big as the sexual revolution. Remember that most of the flappers went on to marry and have families after a few years of being wild and most of the women doing mens’ work during World War II went back to regular life after the war. I suppose that the divorce rate spiked during the 20th century and the Pill was a big factor, or we were told it was. But now people aren’t even getting married. It seems like a big leap to me.
And when we thought it couldn’t get any worse, the government is be ing crueler and more oppressive. And never in my life have I seen such a wide cross-section of the population(not just bad guys!) fear and loathe law enforcement.
