Actually "the masses", in America and increasingly in England, don't seem to buy much of this stuff, as evidenced by the fact that they sit in their hands and don't vote.

In fact it wasn't "the masses" who went out and voted for Hitler, it was the respectable upright uptight people. Not so much because they were stupid as because they were looking after number one, and saw Hitler as someone who would put the rough common people and those clever Jews in their place. The kind of people who, still today, if they feel they are among friends, are liable to mutter things like "Well of course Hitler went too far - but he had some good ideas..."
