what changed is there are No family unit like back then. Most kids had a Mom and dad and they went to church and the kids were taught right from wrong.
I agree today the video game and movie industry the leading groomers of this behavior.
What’s changed is that we have had 50 years of indiscriminately tossing dead babies in dumpsters. What kind of message do you think that has sent to a generation and a half of our youngest?
