The City (London, UK financial sector) and New York City (US financial sectors) generate financial instruments from thin air via financial networking relationships. Both rural/city production and distributed demand for economic output in a financial economy are coupled to financial instrument generation best understood as the outcome of financial deal flows.
In this context I have only conducted one political-economic thought experiment: Making New York City into its own 51st State. Until conducting online research today I was not aware that this proposal has a long history. Instead, I heard a remark by a NYC official years ago arguing that the city financially subsidizes upstate New York via the tax burden. As a common sense person, and an electrical engineer, who also studied law as applied folk psychology, I thought, "New York City is a concrete tombstone without the flow of water, electricity, food, and other goods from the rural areas into the region." In other words, financial relations generated between the city and the rural areas are always partly driving the political-economic outcomes. The city is subsidized by the rural production. The rural production is motivated by financial instrument generation typically accelerated by populations living in cities.
