What was the most important reason why there was little opposition in Germany towards the Nazis regime?

In a Dictatorship such as Nazi Germany, all news outlets were carefully controlled and censored by the Reich Press Chamber a sort of censorial think-tank . Nothing that was oppositional to the Movement was permitted,. one notices the heavy organized crowd presence of Goose-stepping, drumming martial music, this could be on pre-recorded tapes and could be Cut-in) one radio broadcasts to drown out dissenting crowds shouting say (Down with Hitler) and the audience would never know the difference, the big deal on uniformity and conformity= Sieg Heil! could also be drummed into action. Open-line talk programs, so common in the US (for example Open Forum on religious stations, etcf, talk shows) did not exist in Nazi Germany. a very tenuous release valve for (public opinion) was the so-called Wunschkonzert or request concert- but even this was limited to tame Classical Music and vocals that were (Table ready) for public consumption. on the other hand the lively martial music would drum up feellings of unity- but would muzzle dissent. read the Goebbels diaries for more information on how public opinion, which might be negatively defined as controlled response to the party line (the public is taking up Total War very well!) than Public Opinion (with all its faults) in the western sense . Such a cagy but neatly prefabricated structure existed. it was difficult to tell documented (fact) from wishful thinking from Dr. Goebbels Propaganda machine. and so it goes. The Goebbels book is instructive reading on what we woyld now call (manufactured consent) it went far beyond the massed martial music, but that was, of course, a component.
