If we had gold standard:
1. There would be deflation.
2. Deflation would mean that rich investors would hoard dollars instead of spending them, meaning that very little investment would be done.
3. China wouldn't be able to produce as much, meaning that they wouldn't be able to build many factories, etc.
4. China would be a subsistence farming economy. America would be the source of computer manufacturing, but only the rich could buy them.
