1. Large amounts of wealth entering or leaving a community is a material change in the conditions of the community. 2. Communities have the right to a say about material changes that affect them, and to block changes whose effects they see as not in their interests. (I disagree with this part). 3. Therefore, it is unfortunate that people with money are able to enter and leave communities as a unilateral, personal spending decision. 4. It is especially bad when government policy tends to amplify, rather than blunt, the ill effects of these decisions on the poorer people who are affected by them. As policy amplified white flight through the interstate highway system and redlining, or gentrification through slum clearance and urban renewal.
