In today's world with the internet you know about the world's problems and can see them develope. When I was a kid you didn't get to know about things until they happened. i.e. Pearl Haarbor, and the Atomic bombing of Japan.
Today you can see the train wrecks developing before they happen. - tom
That is a very good point Capt. Tom. would be interesting study of how things unfold when more people know about them....
