Update: Here's a local letter to the paper that you can contemplate:
"It was a simpler time
Back in the good old days, remember when:
Our flag was respected, both at home and abroad. The government was of the people, by the people and for the people, not of the politicians, by the politicians and for the politicians. Families took care of families, not the government.
Girls in high school did not have children. You felt safe in your own home. Your house was seldom locked or windows closed. The key to the car was kept in the ignition. There was no such term as "drive by shooting." There was no need for a "war on drugs."
Children walked alone safely to and from school. Police and security guards were not needed at schools. Boys gathered at parks, vacant lots, open fields, etc. to play baseball and other sports. There were no knives, no guns and no need for adult supervision. It was a good time to be a boy.
Movies and TV did not rely on sex and violence to entertain; they entertained the old fashioned way. They did it with talent. You had a competent and caring personal doctor, not today's impersonal socialized medicine system. We were paid to work, not to not work. U.S. Grant was a president, not a government handout.
Children were taught manners. Your word was your bond. A person's good reputation was his most prized possession. Defending our country was a man's responsibility. Democrats and Republicans did not hate each other; they were Americans first and foremost. We fought wars for the right reasons and actually fought to win the wars. And on and on.
Today's society has more modern conveniences, but the good old days were truly "the good old days."
Yeah, those wars were pretty good, weren't they? Chaos supposes not so good for those killed in them, but pardon the digression. At any rate, an expanding population will certainly account for the effects mentioned in the letter, and the writer is to be commended for noticing the difference, although seemingly unaware of the reasons for it.
