Crusoe is approached by Friday.  Friday tells Crusoe he gets one fish for every two fish he catches.  Crusoe is being robbed in perpetuity.  He figures it will take twice as long to produce the net.  Even when he does, half of his fish will go to Friday.  Friday is a parasite and Crusoe is the host.  It’s blatantly obvious capital accumulation will take much longer when there is a parasite to take care of.  This can’t be denied.

John arrives on the island.  Friday decides to treat them equally.  He can decrease the perpetuity of theft.  Friday tells Crusoe and John they must give him a quarter of what they produce.  John sees this as aggression.  Crusoe sees his arrival as a benefit.  The parasite can receive more nourishment with a larger host.  Even the anger of Crusoe has been reduced.  He may view Friday as nice, somewhat of a Stockholm syndrome.

Friday likes his situation.  Friday tells Crusoe and John he will protect them if any others come on the island.  Crusoe and John don’t believe this, but Friday is the largest of the three and might be the best for this role, however unnecessary it may be.  Crusoe and John go along with the claim since they are already being robbed.  He knows Crusoe and John will do away with him eventually.  He must enhance his lie.

Friday discovers a primitive tribe on the other side of the island.  He believes he can conquer them, but only with the help of Crusoe and John.  Friday tells Crusoe and John the tribe is planning an attack.  Friday said it’s an “emergency.”  They will have to attack the tribe preemptively.  Friday promises they can take a portion of the tribes produce if they help.  They would like to be the benefactors of stolen goods, so they agree. 

They all get together and plan an attack on the tribe.  They attack the tribe while they are sleeping.  The battle was hard fought.  Crusoe, Friday, and John have conquered the tribe and tell the same story Friday told Crusoe and John.  There are many more people so the amount they have to steal is far less than when Friday was stealing from two.  The three are splitting the loot and are now living comfortably off the tribe.
