Why does racial residential segregation remain a key problem in the United States ?

Explanation:

Very few Americans live in neighborhoods that are affordable, green, close to jobs, and racially and economically integrated—to the point where it is a relatively common view that such communities are an idealistic or utopian vision rather than an achievable goal or national necessity. While most Americans agree that our economic system favors the powerful, there is no broad consensus from the white majority that integration is essential to make our country more fair. Racial integration without economic integration—also known as gentrification—has consumed the urbanist movement with controversy
