Exotic animals are not something poor people eat because they can't afford. It's absolutely the other way around. Exotic meats are mostly consumed by the powerful people as delicacies.
I have no doubt that there are cases of wealthy people consuming exotic meat as a delicacy, but I would bet pound for pound it is largely people in poorer regions without much alternative.
Unfortunately I'm looking for real stats but am having trouble as most of the trade does not keep records, is illegal, etc
