Unfortunately, that's an oversimplification of how the Nazi got their way; they worked more like a conspiracy under a legal umbrella.
Civil servants were mostly kept in the dark, lawyers got circumvented with mobs and summary executions, only a handful of doctors were aware of what was going on, businessmen... are everywhere, still fine with convicts working for scraps... only select trusted bureaucrats were ever involved with paperwork directly involving murder.
The Nazi weren't harder pressed, because the general sentiment of the society was willing to explain away any criticism... and I'm afraid humanity hasn't fully learned the lesson yet; plenty of present day societies harbor similar sentiments, and are equally easy to weaponize.
