1. Producing in China is cheaper, so companies move production and jobs there.
2. China sells to the US while the US sells nothing to China but dollars.
3. This is possible because the US can print as many dollars as it pleases.
4. And that is possible because we left the gold standard in 1971 and unemployment has been growing since then, along with our trade and fiscal deficit.
If we had gold standard:
1. The US wouldn't print as many dollars as it pleases. and we wouldn't carry a trade deficit.
2. China wouldn't be able to sell so much to the US without buying something back.
3. Production and jobs would move back to the US because without trade imbalance it wouldn't be possible to export so much from China.
