Many college campuses have reacted to Donald Trump’s election with shock and angst. Professors and students are wondering how the rest of the country could be so different from them. The more introspective are asking: What can we do?

Michael Bloomberg has an answer.

It’s an answer that should appeal to both liberals and conservatives — an answer that isn’t about Trump per se but instead about the alienation that helped him win. Bloomberg wants to make leading colleges more open to the working class. He wants to make them fairer places that look more like America.

Top colleges are already diverse in some ways, of course. They enroll students of every ethnicity, from around the world. Yet those otherwise diverse student bodies remain distressingly affluent. Worst of all, they remain affluent even though many poor and middle-class students could thrive at top colleges.

A landmark recent study found that most highly qualified low-income students don’t attend one of the country’s roughly 250 top colleges. Many instead enroll in local colleges with relatively few resources and high dropout rates.
