I don't believe the OP said he had lost any sleep over it or had tried to burn their house down, he just made an observation about our changing culture, and I'm sure he's a bit stunned since it has changed this much.
I know it has a lot to do with religion, but I recall a similar set of values among adults in my youth whether they were religious or not. There were the rough necks who didn't give a care about anything, and then there was everybody else.
There was white, black, blue collar, white collar, etc, but if you were a mature human being trying to lead a decent life, most all I remember shared very similar values. If someone did slip up, which people do sometimes, people didn't throw a party to celebrate it.
When I was young, people used to admire people who had led a clean life. I could name many, many of the older generation I knew that people admired so much for that very reason. It was something to be proud of.
These days, if someone has led a life of old fashioned valuesl and act like they're the least bit proud of it, people call them sanctimonious; no party or pat on the back for them; however, if someone can slip up a little, it's time to throw a party.
I've noticed in my neck of the woods a few old timers even getting lax, but when your kids and grandkids do everything under the sun, I guess what they stood for all their earlier life is not so bad anymore.
By the way, Bigfoot, I'm with you; I graduated from the old school too.
