Whatever else organizes city politics, economies, or modes of governance, dedication to growth is the main political force at work—according to the widely influential “growth machine” thesis. Growth interests, it argues, especially dominate in countries like the United States, where land and buildings operate as private markets, rather than held in common by government or some other entity; most studies have been US based but many commentaries and analyses have followed on from research elsewhere. Researchers describe pursuit of growth in payrolls, capital spending, or construction activity. As in the classic Marxian framework, such would enhance “exchange value.” In the political sphere, growth interests form up at nested scales where they pressure for advantageous zoning and public infrastructure investments at relevant administrative levels—in roads, sewer lines, and so forth. They lobby and help finance campaigns. Opposition forms up, in turn, from those whose interest in the city is primarily for home life or shared enhancements—represented by civic groups or, increasingly, environmental organizations. They strive for gains, again from the extended Marxian lexicon, in “use value”—substantive public benefits, as in health care, libraries, schools, safety, and parks. The resulting debates, studies, and applications are subjects of hundreds of articles, reviews, and books.
