I think it says something quite dark about our society as a whole that we have basically commoditised distress and are encouraging some people often themselves in dire circumstances to prey on others to the benefits of the middle men. I find these new pimps scarier than the old sort in that they pretend to have clean hands.
A plausible scenario might be an FBI agent paying a confidential informant without creating an unexplained income stream. The FBI and friends disclosed spending around $0.5B on informants. The truth could be more. We don’t know what other agencies around the world spend. I imagine they aren’t putting cash in brown bags under park benches.
