why don't the owners of the ship offer less in salary, and pocket the profits for themselves and/or lower the price of the crabs? its the same analogy.
The crew accept the chance that they could catch nothing and get no money. They usually end up getting the qualified crew cheapest that way.
The processors know they will have a certain amount of work to do based on the set quota and set price for the ccrab. They hire unskilled mexicans cheap.
The fishermen & processors are 2 completely separte business entities.
Here many fisherman work on shares. with the owner of the boat getting two shares while the rest get one.
