If the people in the Great Plains are going to be subsidised to do something, does it not make more sense to subsidise jobs in the construction and assembly of power plants and the generation of clean power rather than an unhelpful distortion in the world's agricultural markets?

ECONOMIST: Regulating radio

This provides maximum power of the loudspeaker, without distortion.
