Problem
Economists sometimes say that protectionism is the "second-best" choice for dealing with any particular problem. What they mean is that there is often a policy choice that is more direct or effective for dealing with the problem-a choice that would still allow the benefits of trade to occur. Explain why protectionism is a "second-best" choice for:
a. helping workers as a group
b. helping industries stay strong
c. protecting the environment
d. advancing national defense
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
