I saw that remark too, but from an entirely different perspective. I don't agree with government subsidies, but I strongly support the sovereign right of each nation to establish policy within their own borders. In the referenced post, the WTO, not our government exercised policy making decisions.
Uh, no it didn't. At Cancun, the G-20 walked out of the Doha round over farm subsidies. The G-20 said it would not participate in any future negotiations unless the EU and the US largely ended its farm subsidies. The EU and the US both then made its own decisions to end its farm subsidies, although, of course, we haven't done anything but lip service yet. We'll see what happens over the next year or so and if the round is completed.
The WTO didn't exercise policy decisions--the US government did. The US government decided (wisely, I might add) that it was important to complete the Doha round. So they eliminated the farm subsidies. No one but the US government decided.
