Explain how race is used as a way to (1) control immigration and (2) manage labor supply and markets. How have definitions of race changed to create or restrict economic opportunities in the United States? How has race been used to define national identity in the United States? How does the historical connection between race/ethnicity and national identity continue to define nativist reactions to immigration in the United States? Compare this reaction with nativist reaction from one other country. How do these examples differ? How are they similar?
