Answer:
The answer to the question of: Which ethnic groups would have most likely suffered economic inequality in the post- World War II period, is: D: African American and Native Americans.
Explanation:
This has been a reality for both ethnic groups almost from the very start. The first one because of segregation and discrimination and the second, almost because of total discrimination. In the case of African Americans, almost since they achieved abolition of slavery, they faced economic inequality because they were considered inferior to white people. As such, they lacked job opportunities, and were usually pushed to the fringes of society and given less chances to improve their financial status, than whites. In the case of Native Americans, in some ways, it was even worse, simply because they were almost completely isolated from American society into their reservations, where, the commonality, was to find poverty, lack of employment, and financial chances for improvement. And this was not just after World War II; this inequality on both minorities has happened almost from the beginnings of the United States as a nation.
