I'm sorry, but this analogy is too loose for me; I must rebut.
Suppose the toolmaker maintains these profits by keeping his thumb on the wood-seller who can barely support his family selling 80 cent pieces of wood. If the toolmaker paid the wood-seller $1 or $1.30, this would be more in line with what the wood is worth. The fairness of these price points can be argued.
Now we're back to considering whether engineers are underpaid!
