I can't speak _specifically_ to ethanol, but there are good reasons for the US to provide various subsidies to farms. A visceral example -- if there is a large "world war III" and the US doesn't have a strong Agricultural sector, we could be screwed. It is worth keeping domestic agriculture strong, to hedge against the case where we can't buy produce from other countries. I suspect ethanol is a subset of this general approach. Worth noting I'm no expert, this is just my extremely layman understanding. some more discussion on this here: https://en.wikipedia.org/wiki/Agricultural_policy_of_the_United_States https://en.wikipedia.org/wiki/Agricultural_policy_of_the_Uni...
