Which ethnic group faced the greatest change during WWII? Why?

When the United States entered World War II in late 1941, the largest racial minority group in the United States was black Americans. They made up about 10 percent of the general population. After being freed from slavery only a few generations earlier, blacks still faced daily racial discrimination. Hope this helps!
