sorry to disappoint you, but the biggest manufacturing plants are owned by Chinese. Currently these huge companies are Chinese.
If you know Korea, they used these large corporations to pull their economy, and in a way it has created this almost monopoly, that much wealth is concentrated in Hyundai, Samsung and more.
China is so large and early in the process, our companies are not as powerful, but we got many times the number of theirs.
So not only will there not be joblessness, but China is needing more people from Vietnam, Philippines and other such places that will work for a wage that's even below our standards.
