There don't seem to be subsidies for Pork. There was a "Small Hog Operation Payment" last century that paid $10 per hog for the first 500 hogs sold by a farm, according to wikipedia, but they got rid of that a long time ago. That is well under 10% the sale price of a hog.

The problem mushrooms have is scale, much like spices. We can grow 20K acres of mechanized corn, but mushrooms are a little less mechanized. So its to be expected for mushrooms to cost as much as basil or cilantro per pound.
