discussions needed

1.What economic principle justifies the high salaries of some professional athletes? Suppose the manager of a baseball team wants to hire a new pitcher for $4 million per year. Under what circumstances would it make sense for the team to do so?

4.Several cities across the United States have passed legislation to raise the living wage. How would this policy affect firms? Make an argument for or against living wages in your city. Be sure to cite your references. (Note: the living wage calculator is a useful tool to determine the cost of living where you live).
