Iif you want to make a comparison I have to tell you that the Ndrangheta is the strongest of all.
He replaced the Sicilian Mafia in the drug traffick, also unlike the Cosa Nostra, the ndrine being founded on blood ties, have so far been immune to the pentitismo.
The Calabria is also the poorest regions of Italy; and making an estimate, there are about 7000 ndrine members on less than 2 million inhabitants, a criminal every 300 inhabitants.
