a comment on my article at American Thinker :

Then there is the “expert” assumption of academic economists who are fond of saying things like “assume a perfect economy.” A joke written in reply to this conceited habit a tale of three men washed onto a dessert isle with 3 cases of canned food. The three are a chemist, an engineer and an economist.

The chemist takes some plants, boils them to create an acid which he then uses to eat through the cans’ metal top and acquire food.

The engineer makes a fulcrum from some wooden sticks and a rock, creating a device that smashes the can open from the side.

The economist sits there and says, “Assume a can opener” – and proceeds to starve.
