How come white folks go into a white hot rage and fight tooth and nail against any efforts to build affordable housing within 5 miles of their house?

White suburbanites expect their home's value to increase indefinately. It's an "investment." Even though it doesn't fit out conventional understanding of capital, it functions similarly. They come to believe it's their right to derive money from their ownership of property, and will fight as hard as they can to ensure both the value and their ownership of the property.
