Hyperelastic, point by point:
1 - If you’re talking about the oil producers, yes, they do face a long term decline in their standard of living. They’re supply regions, with an economy dominated by the output of a single commodity with little value added. Not much going on outside of their resource sector, so yeah, the future for them ain’t great. It doesn’t just lead to future instability, it lends itself to present instability. That’s why the ME is the way it is, IMO.
2 - Patent laws usually would apply here.
3 - Ditto here. For intellectual property, the WTO is supposed to have enforcement mechanisms in place, allegedly. But this is a huge weak spot in the international trading system.
4 - Another huge weak spot. We’ve gotten to the point on these boards where people are justifying child & slave labor. There is a line that has to be drawn here, but where that line is drawn should be subject to international negotiation, because you can’t expect Third World countries to maintain First World standards in worker safety and the like. OTOH, demanding adherence to an international standard for child labor and for the outlawing of slavery should certainly be a minimum, I would think.
What is going on that has a lot of people exercised is “commoditization”: that is, processes, workplace skills, and products that were once exclusively First World are now being commoditized and repackaged as outputs from Third World areas. This is a natural process: economies are constantly shedding old outputs and gaining new ones. However, intellectual property rights do have to be respected, and some minimal standards for how products are output have to be maintained. And, of course, abuses like the currency manipulation I pointed out above should be outlawed, with the usual exceptions for emergency situations. None of this would or should get in the way of free trade.
