In Wisconsin like most states cities are creations of the state and transit authorities are also creations of the states. Local tax revenues flow out of cities into the state government for redistribution, which usually results in a net flow of money out of those cities to rural areas, because the cities have the larger economies and the rural areas have a variety of high costs for things like firefighting and road building. The Milwaukee County Transit System, being a creature of the state, derives its funding from the state, which is not always equitably forthcoming. NYC has the same problem with the MTA being controlled by the state government, despite the fact that 97% of the state's economic activity originates in NYC. Any way, if you know anything about American history then you know about the phenomenon where a surrounding entity like a county or state arranges to extract money from a city while also starving it of services. St. Louis is probably the most notable example. Blaming such a city for its own transportation system, while also suggesting that those cities need to spend their own capital to provide parking and driving opportunities to rural citizens, just underlines how little you understand about American cities.
