a. The Bureau of Labor Statistics reports that the median job tenure of an American worker with the same employer has fallen to only 4.3 years. This suggests that the typical worker switches jobs frequently and has many different employers during his/her lifetime. If so, does this make an investment in education (e.g., a BA degree or an MBA degree) more or less valuable to an individual worker?

b. Businesses that sell their products at average prices below their average costs lose money and eventually go out of business. However, price less than average cost is precisely what is true in public higher education, where the prices students pay are well below the costs expended to educate them. However, very few colleges and universities (public or private) are going out of business. Why not?
