Haiti - the plantation where the slaves were never freed. From time to time, the ownership of the plantation changes hands, then the owners are always absentee, stepping on the land only to survey their ill-gotten possession, and to make promises that are never kept.
Feudalism is alive and well in the 21st Century.
Haitians would probably be better off under feudalism.
Haiti is closer to tribalism than feudalism.
Gangs are simply developing tribes.
