This is important, and politically difficult. I mean, we subsidize farms to farm in America because it makes us much more secure against all sorts of potential problems. I, for one, think farm subsidies, if well done, are a very good use of my defense tax dollar.

But it's important that we see those subsidies as a defense subsidy and not, you know, just a handout to a particular class of people; This means that we need sustainable farming practices and we need crop diversity, as those are the only way to defend against some of the threats we face.

(I mean, I personally see it as "you don't want a subsidy? do what you like. But if you want a subsidy? you have to follow these best practices." then you set the subsidy numbers based on how many acres you think we need for that sort of thing.)
