Yes, I remember the world you described. At the time we did not know how really wonderful it was. I feel sorry for kids today. With all their computer toys they will never learn how to play.
I’m a public school teacher. My experience is that kids have almost no attention spans today. Cheating on tests is considered normal behavior, and if you are caught it’s because you did something stupid. That’s the only sin.
There’s no morality. No right or wrong, only “what works”. My high school kids live in homes where their mom has a boyfriend. Divorce is the norm.
What a world the liberals created.
My eldest grandson just HAD to have a "Game Boy;" (I guess, in the same way I HAD to have a BB gun) and finally wore his (divorced) mother down. He became a social recluse with that thing. But some years later, as we watched the younger grandchildren playing at a family gathering, he turned to me, and said, "These kids just don't have the imagination we had." I guess these things are relative, just as the author's 70's seem as innocent as our 50's.
