Caribbean Pirates had a Better System of Government
The average old-timey Caribbean-type pirate ship during the 17th and 18th centuries consisted of 80 pirates, and some pirate crews reached into the hundreds.
But pirates were not known for being the most orderly people.
How did ruffians who thought nothing of murder work together to relieve massive armed merchant vessels of their goods? And how could one pirate be sure his hard work wouldn't simply be stolen by a rival, or expropriated by the Captain?
Caribbean piracy was effective and profitable, in short, because they formed an effective legal system. Pirate ships were like tiny floating governments.
And while pirates were clearly horrible to outsiders, internally, they actually had a fair and efficient system of governance.
Each ship would put together their own set of rules or articles. These essentially formed the government aboard each ship.
for pirates robbing was work they had to rob or they would be poor and starve, you say they had a better system of government, but do you know what a high mortality rate they had? they died like flies.
