This is an extremely odd thing to say about authoritarians right now, although this may be my American perspective, since people have been pointing out recently how futile it can be when dealing with police in the US. Still, I kind of think it's universal - being polite to authority is utterly useless once you are a suspect, thought to be dangerous, or have something they want.

It made a lasting impression on me when I was stopped in my car as a teenager and an officer decided that I must be a drug smuggler because I was too quiet/nervous.

Edit: I guess if you interpret "everything" broadly enough, your statement is somewhat plausible, but "everything" includes many situations where an authority asks you something that is theoretically or ought to be voluntary and you have to be aware that it's not really a choice. And it's still not always true.
