Poverty pimp
Poverty pimp or "professional poverty pimp" is a pejorative label used to convey that an individual or group is benefiting unduly by acting as an intermediary on behalf of the poor, the disadvantaged, or some other "victimized" groups.
Those who use this appellation suggest that those so labeled profit unduly from the misfortune of others, and therefore do not really wish the societal problems that they appear to work on to be eliminated permanently, as it is not in their own interest for this to happen. It could be applied to someone who sees poverty as a career, and as such alleviation of poverty-related issues would be a threat to their livelihood.
