Salami slicing is the first page of the present day authoritarian play book.
Here's an excerpt from They Thought They Were Free, a book about the mindset of ordinary Germans experiencing the rise of the Nazi Government:
Each act, each occasion, is worse than the last, but only a little worse. You wait for the next and the next. You wait for one great shocking occasion, thinking that others, when such a shock comes, will join with you in resisting somehow. You don’t want to act, or even talk alone; you don’t want to “go out of your way to make trouble.” Why not?—Well, you are not in the habit of doing it. And it is not just fear, fear of standing alone, that restrains you; it is also genuine uncertainty.
Uncertainty is a very important factor, and, instead of decreasing as time goes on, it grows. Outside, in the streets, in the general community, “everyone” is happy. One hears no protest, and certainly sees none. You speak privately to your colleagues, some of whom certainly feel as you do; but what do they say? They say, “It’s not so bad” or “You’re seeing things” or “You’re an alarmist.”
And you are an alarmist. You are saying that this must lead to this, and you can’t prove it. These are the beginnings, yes; but how do you know for sure when you don’t know the end, and how do you know, or even surmise, the end? On the one hand, your enemies, the law, the regime, the Party, intimidate you. On the other, your colleagues pooh-pooh you as pessimistic or even neurotic. You are left with your close friends, who are, naturally, people who have always thought as you have.
...
But the one great shocking occasion, when tens or hundreds of thousands will join with you, never comes. That’s the difficulty. If the last and worst act of the whole regime had come immediately after the first and smallest, thousands, yes, millions, would have been sufficiently shocked—if, let us say, the gassing of the Jews in ’43 had come immediately after the “German Firm” stickers on the windows of non-Jewish shops in ’33. But of course this isn’t the way it happens. In between come all of the hundreds of little steps, some of them imperceptible, each of them preparing you not to be shocked by the next. Step C is not so much worse than Step B, and, if you did not make a stand at Step B, why should you at Step C? And so on to Step D.
