What comparisons can you make between Nazi Germany and the society in 1984?

I think the key similarities are hero worship and, closely
tied to it, their use of propaganda.  Many Germans never saw Hitler for what he was;
they continued to "trust" that he would resurrect their hopes.  This was as much due to
his charistmatic leadership as it was to their need for redemption from the humiliation
of WW I.

The use of propaganda was even more masterful. 
Just as history is "created" in 1984, so Hitler's propaganda machine run by Joseph
Goebbles made sure that no information got to the German people that was critical of
Hitler, the regieme or anything detrimental to their programs.  Just as BB felt free to
"change" the past, or what people thought to be the past (this is a very complicated
issue), Hitler invented facts to support his ideology and politics.  He made especially
good use of the new medium of film ... and you have to wonder what he woujld have done
if television were more widelyl available.

Of course, this
goes on in our time as well, which is why the book is so frightening.  It used to be
difficult to find the truth because information was so hard to come by; there is now so
much information on the internet that it's difficult/impossible for us to know what to
believe.  So politicians, especially in the election cycle, create realities for us. 
For example, we have recently been told that the policies of the present administration,
while not seeming to work, prevented our entering a depression.  How do know if this is
true?  How do they know if this is true?  But it is convenient, which is kehy to BB's
manipulation of the facts.
