Chinese manufacture is, unfortunately for American labor, not junk. Of course iPhones and other electronics, but good-quality musical instruments and optical systems are among the competitive products. There was a conscious industrial policy of a target being 80% of the quality for 50% of the price. Most budget guitars, violins, and mandolins, are Chinese (or other Pac-Rim nations).
That horse left the barn long ago. Too late for simple protection, but incentivizing and supporting American labor and manufacture is still possible. The greater challenge is robotics, but for now, the competition for cheap labor is hurting Chinese, who are losing some manufacturing jobs to Vietnam and other developing nations.
Manufacturing is actually doing ok here, but not adding jobs. Cars are still made here but use 1/10 the workforce. That is due to automation. But some home conveniences also lost jobs. Desktop publishing pretty much killed the small print shops. China is not the sole cause of our job situation. The cause is unregulated progress in all areas. We can't hide from the world, but we can apply some "friction" appropriately to soften transitions. It is the surrender to corporate bottom line that the GOP (mainly) enabled that is the cause of the decline of unions and supported labor.
