Authoritarian state monopolies suppress local mafia organizations [causal]
The latter, through the example Hawthorn gives of South Korea, consists of an authoritarian and military rule which, in itself monopolistic, would not tolerate local monopolies. In a sense, this implies that in order to get rid of the mafia, what we need is simply another — bigger and better — mafia.
Builds on: "Mafia-averse emigration unintentionally concentrates and strengthens remaining mafia power."
