The money would be better invested in the development of affordable public transportation.
This and perhaps there be ways, if possible, to encourage/subsidize the rural poor to relocate to more developed areas.
Or we could
identify and pursue policies that genuinely help rural areas, instead of encouraging rural communities and cultures to (continue to) self-destruct because rectifying their problems seems too hard. The more I think about the subject matter of this thread the more I come around to the subsidized ride-sharing concept, for example. Comparatively well-settled countryside--as in, northwestern Massachusetts and east-central Iowa rather than northern Maine or western Kansas--could also sure as the sunrise have better bus service than it generally does; trains aren't the only kind of mass transportation available. The unsustainable environment that ought to be crusaded against is, and I think traininthedistance (who's the only real expert on transportation policy I'd say we have here) would agree with me on this, the cul-de-sac, not Rural Route Insert-Number-Here or the holler. Not that this is where suburban development in this country actually originated conceptually, but 'eliminating the distinction between town and country' was one of the ideas where Marx, while well-intentioned, went disastrously wrong.
