The Omnivore's Dilemma is playing out now in Congress over the latest package of farm subsidies.
In an excellent op-ed in the New York Times, the author of that book makes a clear case against current agricultural policy. And then he turns the tables:
How could this have happened? For starters, farm bill critics did a far better job demonizing subsidies, and depicting commodity farmers as welfare queens, than they did proposing alternative — and politically appealing — forms of farm support. And then the farm lobby did what it has always done: bought off its critics with “programs.” For that reason “Americans who eat” can expect some nutritious crumbs from the farm bill, just enough to ensure that reform-minded legislators will hold their noses and support it.
Cascadia Report has found farm subsidies to be an easy target, for example here and here and here. We're waiting for some good policy to praise.
