I've known people who were not in any position of power, in fact they probably saw themselves as victims (not socionics victim), but they tried to get money and other services from others by being manipulative, playing nice and all that.
Well even still, I don't know why they should be blamed for that. If that is the thing of value they have to trade for something else, I don't see what's so wrong with that. You may wish they were more logical and traded in more realistic skills for those things, but that might not objectively be their best asset to sell. I don't even think they necessarily saw themselves as victims, I think more that's just how you perceived them. If they were really in victim mode, they wouldn't try to do anything at all to get ahead- not even be nice.

Therapists and social workers are often incredibly manipulative, lol- it is naive to think otherwise. With this tho it allows them to do their job and give it the air of authority it needs.
