How did the great depression improve the native americans' organization?

Before the Great Depression and the Indian New Deal, ethnocidal policies devastated Native-American individuals and nations. Between 1887 and 1933, over half of the tribal land base was lost to land thieves, tax sales, and governmental sales of "surplus lands." These policies launched a cycle of poverty that continues at the beginning of the twenty-first century. Thus, lack of education and ill health became hallmarks of tribal societies in the United States. But these racist missionary and civilizing policies did not bring the benefits of American civilization to Native-American people. Instead, many native peoples strengthened their resolve to nurture and cleave to their old traditional ways.

Ithink it's b . narratives cannot be changed by other historians later
