The quick answer?
Geography. The U.S. is bordered by two large oceans.
Raw materials: Where Germany and the Axis powers had to invade to obtain the materiel to either make, or run their war machine (reads gas, oil, & steel), America had stores of natural resources....that and the fact that our vast oceanic borders kept the raids on our war machine/factories at bay----not so the axis. We took the war to them.
Mass production: Borrowing models based on the Henry Ford production line of interchangeable parts....we simply overpowered the axis with our ability to mass produce guns, bullets, and beans. We had a liberty ship going down the skid way every week. While Germany made magnificent weapons, particularly their tanks(armor) and Navy(uboats).....they took much longer to build based on their complexity, and then, there was the matter of fuel consumption to run them, and their ability to repair them...complex equipment need complex parts to make them run again, and they simply couldn't pull one off the shelf. By contrast, the U.S. out-produced the axis based on that Ford model.
Yamoto said it best after the attack on Pearl Harbor; "I fear we have awoken a sleeping giant......"
You knew the answer before you asked the question Rooster. It's human nature, when there's no accountability especially for some people, when there are no fences to make good neighbors......that and the more salient fact that, anonymity from a computer room hundreds and thousands of miles away from center mass, and a lack of face to face accountability. It emboldens everyone with their own small sense of security. Now....if the computer cops could kick in our doors and shine a bright flashlight on us all for the things we say, I'd like to suggest that the answers we give would be more reasoned. Of course, having prepped for just that eventuality, I took it upon myself to hide the batteries for the flashlights .....but you get what I mean.
You'll never remove the stimuli.....in this case anonymity, unless the one condition to joining a website was to have a camera attached to the top of your screen, but even then.....
I also have a theory of course, one which I believe I'm spot on with, and that is the belief that for every one of those who belong to either one or a number of sites, they are dwarfed by those who lurk. I think lurking is THE number one past time of people who know all the opinion based web sites.....once you're infected, you're either a voyeur or that moth attracted to light.
And of course, no one ever attached behavior to it's wings.
From a 2016 opinion piece by Louis Menand of the New Yorker, which I think is an excellent article....and the warning of what happens when you choose a group of intellectuals like the Young Hegelians and a career in Philosophy over Law.
Well.......how can you qualify that? There's always gonna be the "next best thing." I think the mystery surrounding her early demise tends to lend more of that infatuation value certainly. And secondly, she was seldom measured in terms of beauty above her shoulders IMO. What I do know, and have read is that she became tired of that, and being seen as "that blonde." She was actually quite intelligent and I'd have liked to have seen her take a Mensa exam to find where she would have wound up on the scale. I've read some of her poetry and it was well done.
The worst thing that happened to her in my opinion was in getting mixed up with the Kennedys. Most people don't know that both JFK and brother Bobby were taking turns tag-teaming her....not to be outdone in terms of libido by none other than little Miss Camelot, Jackie Kennedy. I had read that she became privy to information that ended up costing her, her life and that her death was made to look like a suicide. Fascinating stuff if you're in to that sort of thing.
