The parts of the "countryside" that do not get federal water subsidy fall into 2 categories: (a) places with water already, and (b) places that arent populated.
Now lets not confuse cause and effect. It is only through water subsidy that the unpopulated areas, such as deserts, will ever become populated. There does not exist a need for water subsidy in places where there has never been water subsidy before. It is only in places that have previously received water subsidy that now have a need for it, such as the arid regions of the midwest that are now in perpetual water shortage mode.
So the federal water subsidy is harmful. It alone creates the need for itself.
Why are any other subsidies different? If you decide to build your house a hundred miles from the nearest electricity, why do you expect anyone else to foot the bill to hook your dumb ass up to electricity? If you expect that, fuck you. People that expect that are fucking assholes that dont deserve any respect at all from anyone, certainly not respect from the people that these assholes so selfishly and greedily expect should have to pay.
