I'm in the dictator camp I think. But a fair dictatorship, if that makes sense. (probably doesn't.) I like Zahnburg's post, that sums it up well I think.
Ideally, sure, I want my dog to *want* to do what they're being told, but bottom line is they *must* do what they're told. I'm strongly bonded enough to them that they know I mean what I say, so they don't often "question" it, it is just expected. They might be rewarded, they might not. If they do not do as told, it won't just be ignored. That's the hard part, with dogs AND kids

-- it's too easy to give up and let things go, but that's such a recipe for problems.
