The Pirate Stock Exchange, from Craig Mee
A recent BBC documentary revealed how ingenious pirates have set up a pirate "stock exchange" to encourage investors and build an economy, albeit a black one. Pirate groups of a certain size register themselves in the same way that established companies can on a regular stock exchange. Individuals can then choose to invest in one or more groups, by donating weapons or buying shares. They then get a cut of the earnings when their pirate group strikes lucky.
