A logging company exports its wood-finishing jobs to its Indonesian subsidiary and lays off the corresponding half of its Canadian workers (the higher-paid half). It clear-cuts 95% of the forest, leaving the rest for the spotted owl, and lays off all its remaining Canadian workers. It tells the workers that the spotted owl is  responsible for the absence of loggable trees and lobbies Parliament for exemption from the Endangered Species Act. Parliament instead exempts the company from all federal regulation. What is the return on investment of the lobbying costs? Extra Credit: DO in conjunction with someone from Public Policy Background.

A company outsources all of its loggers. They save on benefits and when demand for their product is down,   the logging work force can easily be cut back. The average logger employed by the company earned  $50,000, had three weeks' vacation, received a nice retirement plan and medical insurance. The contracted  logger charges $50 an hour. Was outsourcing a good move? Answer is always YES.

A logger exchanges a set "L" of lumber for a set "M" of money. The cardinality of set "M" is 100. Each element is worth one dollar. Make 100 dots representing the elements of the set "M." The set "C," the cost of production, contains 20 fewer points than set "M." Represent the set "C" as a subset of set "M" and answer the following question: What is the cardinality of the set "P" of profits?
