Happiness is more closely linked to status (relative position and wealth) than absolute benefits[1][2]. In that respect, I imagine someone taken from the environment they understand and are accustomed to and put into a foreign one where they are likely a curiosity, and at best an outsider, would result in them longing for what they understood.

For the same reason, I imagine the poor in Benjamin Franklin's time might find a Native American lifestyle (if accepted by the group) to have some draw if exposed to it. I would by the same measure expect the middle and upper classes to find it less appealing.
