"The question is do you trust markets (product markets, labor markets etc.) to adjust quickly enough to ensure an equilibrium in which those markets clear at an adequate level.
Economic theory says that if markets function well enough, they will clear at a competitive price. Now if manufacturing jobs are too expensive in one area (and it is not absolute expense which matters, so no, not all jobs will go to China because you have to factor in relative productivity and other cost factors) they will be migrated, which is an eufemism for people will loose their jobs in one area and get new jobs in the other.
The displaced workers in area A (let's say for arguments sake this is America) will now have to seek new jobs at a new wage rate determined by their skill level in a new area of work. This is a painful process.
If area A does not create sufficient new jobs in other market segments (not necessarily services, it can be higher grade manufacturing), the price of labor in area A will drop in order to adjust and clear the market at the new price level.
But in this case, the USA is very effective in creating new jobs in higher value added segments. Apart from a business cycle slump, there is no structural stagnation in the US economy. And, as all consumers can now buy the manufacturing products from area C (let's say China) at a lower price, their overall buying power increases and their demand for other products and services, many of them created in the USA, will go up.
Take the example of the steel tarrifs. By artificially attempting to stop the migration of US steel jobs to other areas, the price of steel in the US went up. Sectors using steel as a an input product had to pay a higher price for their materials, and became less competitive as a result. As these sectors like car manufacturers are much larger than the steel industry, the effect of the steel tarrifs has been a net loss of jobs in the USA.
The same goes with the manufacturing jobs going to China, and the service jobs going to India. As long as the US stays competitive as a whole, this is a net benefit to the US economy. In addition, as the buying power of these other countries rises, their demand for all kinds of products, many of them made in the US, will go up. The entire world economy, including the US, benefits. This is not a zero sum game, but a question of globally optimising the use of inputs including labor.
Don't fall for scare mongery. Trade is good for everyone, and the loss of jobs to China is acceptable, if there are no market disturbances that prevent the clearing of markets. So, if the Chinese are manipulating the value of the remnibi (which they are) there may be cause for concern.
Just two words of caution:
- People that are being hit with this displacement are always in a world of pain - there's no denying that. Economic theory is fine, losing your job is not.
- All this hinges on efficiently operating markets - which may not always be the case. If there are significant market disturbances, better double check your assumptions. "
