Sorry for not getting back to you sooner - have been out of town for a while.
Nor have the Republicans when it comes to agriculture. In spite of your comments regarding free flow of money and intellectual property opening agriculture trade would be a first step to helping the third world.
Not that I'm defending the Republicans (heck, that's as close to a capital offense as we have up here in Canada), but they're at least participating in the Doha talks. There is a huge push on right now to get something done, because the Fast Track Trade Authority given to the President sunsets this June. After this deadline, it's widely expected that the Democrats will kill any further liberalization of trade, there's also definite rumblings from the Democrat camp about seeking additional protective measures. 2008 isn't looking too good.
You can always tell an economy is headed for a correction when the mental lightweights start talking about economic "protective measures". The ironic thing is, those protective measures just make the correction that much worse. If it wasn't so sad it would be funny - the US is all hot and bothered about China's trade imbalance, but yet they're not putting 2 and 2 together by figuring out that the trade imbalance is financing the US debt! If China stops buying US debt, America will have to find other buyers, which means interest rates will have to go up to attract these buyers, which means the economy will really go in the crapper.
As far as whether it's removing ag subsidies, protecting IP so that companies will go into developing countries, or cross border money movement that is the critical thing to help under-developed countries get a leg up - I think it's dependant on the country itself. A country that has poor agricultural lands, but rich in minerals doesn't need 1st world ag subsidies lifted, they need foreign investment in order to develop those resources.
We need to get a move on in all three areas.
