Recently I did some reading about how Chicago neighborhoods were affected by redlining (The practice of not granting mortages to minority borrowers) after World War II and have become basically bombed out and impovershed. This tended to coincide with White Flight and the expansion of the "color belt" as the minority populations grew and local economies were destroyed. Urban Poor grew to affect an area much larger than the Inner City.
In the mean time, the suburbs exploded and even some city neighborhoods went sprawl. We now see the downfall to this and the cost to reclaim our past.
However, many of the redlined neighborhoods have maintained at least a ghost of their past glory. High density building, integrated commerce and residential areas and public transportation. The face that these neighborhoods were destroyed the way they were is a shame but they now present an excellent option of redemption.
Now I'm not just talking regentrification and redistribution of the poor. Let people stay where they want. The goal should be to get people to want to live in these neighboorhoods.
Perhaps people could discuss motives to get people in, preferrablly in a mixed ethnicity, mixed income way and get them to start their own urban renewal? Including an involved civic structure in the style of Putnam and Kunstler.
