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.

These are the people you are trying to push out, not the productive, well compensated people.
