Suppose the United States government wants to build new recreational parks along the east coast from North Carolina to New England. The projected revenues from building the parks for the next 4 years will be $150 billion dollars while the projected costs from building the parks for the next 4 years will be $100 billion dollars. What is the net gain or net loss of going ahead with building the parks along the East Coast? Please calculate. Also, based on your calculation, should the U.S. government go ahead with building the parks along the east coast or not and why? Explain.
