I see a lot of growth potential for manufactured goods if you measure them in mass. I'm not sure there's great growth potential if you measure them in money. Every wave of industrial relocation so far has overtopped the previous one by lowering costs. China's steelmakers are exporting more tonnes of steel than US steelmakers did 50 years ago, but they're also commanding significantly less money per tonne. For that matter, if poor countries are going to get wealthier but buy manufactured goods from abroad, where is their new wealth coming from if not manufacturing or services?
