In the country it’s like 40% of the farms and 20% of the value. That stat alone shows the real problem, big agricultural is wildly more efficient (without wading into the externalities). And big agricultural gets the lions share of the benefit of the subsidies.
I’m not even sure that’s a bad thing but half the reason these conversations are so circular is that small family farms are not what most agriculture in the US is yet we vote like it is.
