1. Lets see how much robots can replace of the labour

2. China one accumulated most of the world silver reserves. Buying nothing and selling silk and porcelain. This was one of the reasons for the Opium war. Today China produces nothing that not somebody else could produce. Shoes, Clothes, toys, electronics. They tried to get a monopoly with rare earth metals but this seem to have failed.

I challenge your statement. I doubt the outcome.
