Looks like I’m getting into this question a bit late in the game, but after reading every response (all 138 of them… wow!) I still wanted to say something that hasn’t been mentioned fully.
What has mainly been argued in this post by the OP, as I understand it, is the change in humanity in the past 60-odd years in the USA. This is an incredibly narrow view of the world. Sixty, one hundred, even a thousand years is a greatly insufficient period of time to use as comparison for any aspect of human nature. Humans only developed agriculture ten thousand years ago, and we were hunter gatherers for long before that. That’s a lot of time for human behavior to be ignored.
I agree with those who think we’ve gotten better as far as being “savage animals” go. Because of the the increased law and social awareness people have, crimes of all sorts have diminished. Back before modern civilization, as some have said, simple disputes were often decided by fights to the death.
But in ways, we haven’t gotten better. Because outright violence is no longer socially acceptable, we’ve found different, more roundabout ways of making each other miserable. Instead of killing someone, you can sue them for everything they’re worth. Instead of fist fights, people get harassed verbally or over the internet to the point of suicide.
Brutality is part of human nature. People have always done terrible things for stupid, selfish means – people have killed for something much more petty than an iPod. It’s part of our animalistic nature that we have so desperately tried to hide with our mask of civilization.
In my opinion people in general aren’t getting more savage, we’re just changing the ways in which we already are savage. Chances are, @Rangie, there were just as many people (relative to the population, of course) committing crimes as there are now, perhaps even less – just in different ways and with different media coverage. If there were iPods back when you were growing up, chances are some stupid criminal would kill someone for one at the same time you were casually sleeping in your lawn.
