Oh, go ahead, blame the EU!
It's not like America is not subsidizing its own farmers even more heavily and it wasn't the USA in the first place who tried to enforce free-trade worldwide.
Well, I am not up to date with everything America does (Me is Dutch). Modified the main post.
But mabye we should continue subsidieng everything, because apperently, our farming is not sustainable without it (and it provides simply too much food, so we can't afford to ditch it either, however, it might be toned down still). Allowing underdeveloped countries to raise income fees again should work though.
