"Some" is quite the understatement. We're talking about hundreds of millions here. And slaving away in an assembly line might not be fun, but it's better than starving on the farm. Plus, now that most of the reserve workers pool has been used up (in no small part because China's new middle class need a lot of these workers to satisfy its need), wages are rising. Fast. We're talking about wages doubling every 4 years here.
Actually, wages are raising so fast that Chinese companies are now outsourcing, either taking factories back to the West, or opening factories in Africa, which will hopefully help those guys get out of poverty too.
I am very protectionist. Moreso than you can imagine.
You're assuming it isn't cyclical, but rather a progressive good thing with wages rising....
What if, instead of eventually "running out of people to lowball on wages" the corporations simply rotate who they employ and who they don't (who they starve)? Let's see... we'll move all our factories to China for 20 years, then to Pakistan, then to Africa, then Korea, finally we'll ship some to the US now that we've killed their wage bargaining power..... Do you see how they can boycott round labor?
Your assumption of a constantly rising standard for the future being spread around the world is the opposite of what corporations want. They LIKE cheap as hell labor and they will screw you to get it.
I know all about international economics and Ricardian and Smithian views. That's fine but the problem is that trade needs to be reciprocal. Trade with China could've gone VERY differently where both sides would've gained something, instead of just them gaining a ton of our IOUs / us becoming heavily indebted to them.... The problem with trade to the developing world, is that it is always asymmetrical in practice. It needs to be heavily regulated so as not to exploit the crap out of both sides. So far trade with China has been a lose lose endeavor for the peoples of both countries (not the politicians or companies). The Chinese are now overworked, underpaid and unsafe with 0 worker safety. The Americans are now unemployed and broke. Though China overall came out on top (new society and social infrastrcuture buildings, compared to the decaying ruins of Detroit and the entire "rust belt"...).
