Thoroughly classroom tested, this introductory-level text surveys what economists have to say about inequality (or income and wealth distribution), poverty, mobility - both intragenerational (within careers), and intergenerational (between generations) - and discrimination (on the basis of race, ethnicity, age, gender, and many other factors) in the United States. This text brings the undergraduate treatment of these issues up-to-date, featuring detailed, but not mathematical, examination of the economic theory underlying the analysis. There is a greater emphasis on mobility, on wealth accumulation, distribution and inheritance, and on discrimination law than in other texts. The author provides full and fair treatment of competing sides in several of the controversial issues in the field, written in such a way that instructors can use the text material to motivate a variety of classroom discussions. An Instructor's Manual featuring solutions to the end-of-chapter questions is available online to adoptors.
