In my experience, while most Third World people exhibit feral traits, many (though not most) manage to become at least somewhat human and civilized under the right conditions. The exceptions seem to be Somalis, Haitians, and Hmong, and people from certain Arab countries, nearly all of whom remain feral animals no matter what the circumstances.
Well said. Eastwood in “Gran Torino” might disagfee about the Hmong. /s
