How many people would you vouch for?

I wouldn't call manipulation a form of trust. I suppose it's an alternate means to an end.

If you manipulate someone well enough you're going to trust them with what you manipulated them into doing.

Manipulation is always at work, whether we notice it or not.

I think you need to define manipulation very broadly to make a claim like that, to the point where it's a tautology.
