Editor's note: This post is part of a series by Dr. Baker on Our Values about core American values. This week Dr. Baker is discussing King's dream. Respect for people of different races is one of the 10 core values that nearly all Americans hold dear. But: How well do blacks and whites actually get along? This week, we’ve used the occasion of the 50th anniversary of the March on Washington and Martin Luther King’s “I Have a Dream” speech to reflect on race relations since that time.
