Gentrification?

Question

Gentrification?

Answer 1

Gentrification, or (urban gentrification), is change in an urban area associated with the influx of an income class above existing residents in a lower class.  Gentrification is characterized by several processes. The area experiences a demographic shift to an increase in median income, decline in racial diversity, and often reduction in household size. More households with higher incomes result in real estate being perceived to be more valuable with increased rent and home prices, and conversion of rental units to ownership. Industrial land use declines and is redeveloped into food, retail, office, and high-end residential housing. Lastly, the culture and character of a neighborhood changes.

Answer 2

If it's the definition you wanted, which I doubt, you've gotten it.  If it's the morality of it, it's too natural an endeavor to come under moral applicability.  The middle-and-upper classes often improve and sell, accumulating their profits from repetition and leaving permanent improvement behind, though middle classes are dwindling, and upper classes probably think twice now, with the cost of professionals having risen.  The displaced low classes have money they wouldn't otherwise have had, likely availing them of better housing, and the city profits by raising property tax.  Everybody wins.
