What if it isn't just elites? What if big pharma has been using Haitian children as a drug farm for medications? Looking at what you posted combined with a few sources from a quick search it would appear that melanin can also increase aggression and agitation… basically traits that are more in line with races that already have lots of melanin naturally. What if the "browning" has already been ongoing? Or the side effects of increasing melanin levels over time in a predominantly white society leads to things that have to be "cured" through other big pharma meds (SSRI, antidepressants)?
I beg to differ somewhat. Melanin is used in viagra and other athletic supplements to increase libido, supress appetite, etc. Melanin injected into animals has also led to increased aggression.

Sources are prolly cancer, but… there's a metric shit ton of them out there with the connection to melanin and increased aggression, amongst other things.
