Professor Todd Swanstrom wrote a wonderful article that I read in Urban Observatory. In that article he very intelligently took apart much of the misinformation in St. Louis. Advocates have decried any effort at city development that does not specifically address poor people. They complain that gentrification is moving poor people out of the central corridor and the Tower Grove area. Professor Swanstrom points out the data does not support this assumption. True gentrification requires a substantial increase in housing costs that drive out poor people. This is not happening in St. Louis. The contrary problem has taken place; depopulation of many areas of the city.
You would think we would welcome development with open arms. Oh well!
