What action does Oluo consider crucial in the fight to provide students of color with educations comparable to those of their white peers?

Oluo states near the end of Chapter 13: Why Are Our Students So Angry? that one of the most important actions that can be taken to fight for equal access to high-quality education is to focus on colleges and universities. She suggests that it is crucial for people of all colors to demand that our colleges and universities begin to demonstrate greater diversity within their student populations.
