Most rural areas no longer have the popuation to sustain even a highway bus service on a private basis.
In which case, they don't have enough population to swing any significant votes in a democracy. The malapportioned nature of the US Senate is a problem here, as are certain malapportioned and gerrymandered state legislative houses. Should be interesting to see what changes after the 2012 census numbers are used for redistricting; the depletion of rural areas is finally getting to the point that continuous gerrymandering can't always disguise it. Pro-rural, anti-urban bias in the upper house of legislatures is long-lasting, entrenched before Baker v. Carr, and now maintained by gerrymandering dating from just after Baker v. Carr; though I know the infamous one in the New York State Senate best, and don't know much about other states' legislatures.
It's worth noting that Sioux City's hostility is threatening service not to Sioux City, but to *Iowa City*, which actually needs it, making this a case of the "We rural bumpkins know best what you urbanites need" attitude. Do they have a claim based on paying taxes? Probably not. Look at where the taxes come from in Iowa. If it's like most states, the urban areas are paying most of the taxes, and the agricultural areas are getting subsidies.
But the bigger problem is not these rural areas, whose population is simply getting too small to matter; the bigger problem is suburban areas which, frankly, do need rail service and are voting against their best interests. I don't really blame the voters. Some of them are a bit surprised when they discover what the politicians they voted for are actually doing, and that's certainly been the case in Wisconsin. I don't think Iowa City is going to be at all happy with Gov. Branstad, and we'll see about the rest of the cities on the eastern side of the state.
