Final answer:
Municipal governments deployed the owner-occupant support sector as a means to address urban decay and increase tax revenue through gentrification, particularly following widespread property abandonment and fiscal crises in cities during the 1960s and 70s.
Step-by-step explanation:
An owner-occupant support sector is put into play on the occasion when municipal governments engage in efforts to revitalize their city landscapes, particularly through gentrification processes. During the 1960s and 70s, urban decay led to high levels of property abandonment. This was compounded by unscrupulous landlords who sometimes resorted to arson to claim insurance money before deserting their buildings. Unable to generate tax revenue from these properties, cities like New York faced fiscal crises. By the 1980s, the dire straits induced municipalities to become major landowners, holding onto numerous abandoned properties.
Gentrification emerged as a solution, helping to restore deteriorating urban areas and bolster municipal finances. Notably, it is within the context of Hoyt's Sector Model that we understand how urban development takes form, with specific sectors designated for various social classes and functions, such as working-class housing or industry.
