As opposed to a future in which sweatshop-tolerant nations can drive our standard of living down to theirs.
You mean like Japan, India, Mexico... Etc...
Sweatshop tolerant nations don't last long in that stage. It is part of the growing process to get out of poverty. Those sweatshops lead to more wealth which in turn leads to higher living standards where individuals have more choices and can start making demands of the employer and win them. Japan was in the same boat in the mid 50's and 60's. Countries don't just jump from dirt poor to a Western style capitalist economy.
Now that the Chinese have produced some wealth they are demanding better working and environmental conditions. In doing so the cost to produce things in China is going up. As they catch up to the rest of the Western world they're costs will start to equalize with us. Japan went through the same process. Enjoy the lower cost of some things while you can. They won't last because the world is running out of underdeveloped country labor sources. In time Chinese economic freedom is going to collide with Chinese one size fits all rigid government. In addition a good chunk of that new found wealth has been squandered on state run top down projects that were useless.
I also find it interesting when free people think they can't compete with political slaves. There's a reason why a free American people have driven the wealth of the world.
