Like religion, education and many other social issues, I think this reflects a broad, fundamental change in our society, not just a specific element. One of the best examples I can think of is "counter checks." Anybody remember those?
Back in the 50's and early 60's, credit cards weren't really around, and everybody wrote checks, except for small cash items. At the checkout counter in any store or restaurant, you saw a little rack of blank checks. You found the ones from your bank, tore off a check, wrote in the amount and signed it.
Usually there were some extra checks in the little rack with no bank name on them. If you couldn't find a check from your bank, you just took one of these and WROTE IN the name of the bank. No problemo.
Of course, asking for your ID was unheard of.
Can you *IMAGINE* doing this today? Utterly, totally unthinkable.
Remember when every boy carried a pocketknife? When kids rode bicycles to school? Remember when there were no chain businesses, no fast food, no credit cards, no cable TV, no voice mail? When "playing" meant "going outside"? Wish I had a dollar for every time I've said, "Mommy, can I go outside and play?" and the streets were swarming with kids on bicycles. Drive down the typical suburban residential street now. It's deserted: not a living soul in sight, young or old. They're all inside staring at a computer or TV, usually while stuffing their fat faces with junk food.
We've lost something very, very special in this country, and we'll never get it back. Some call it "the America Norman Rockwell painted." Sadly, it's gone forever.
Anyway..... when people start talking about how things have changed, those counter checks always come to my mind as an perfect example of how our society has changed over the last few decades.
