A society's collective memory seems to fade after a few hundred years.A few hundred years? Try a few decades.
In the 1940s, the USA fought totalitarianism. Then we had a major fight against Communism. In both struggles, a major part of our self image is that we, unlike the totalitarian states we struggled against, were a free country. If, in a movie in the 70s, you saw the German officer saying, "Papers, please", that was a sure sign that they were the enemy - not living in a free state.
Today we live in a state that would be instantly recognizable as a totalitarian state. Just like past totalitarian states, the excuse is our security. Do you think that I'm exaggerating? 20 years ago it was common to not need an ID to board a plane, with it being reasonably common that the person whose name was on the ticket was not the person holding the ticket. (That would generally be because someone had bought someone else's return ticket because that was cheaper than buying a one-way ticket.) Today you not only need ID, you go through a thorough search and most take it for granted that we might go through a virtual strip search to get onto the plane.
Can I make this worse? Actually, I can. Nobody will show you the law requiring ID to fly. There was actually a lawsuit filed about this. John Gilmore lost, and STILL didn't get to see the law. (See http://usatoday30.usatoday.com/tech/news/techpolicy/2004-03-... for random verification.)
