A few things...
First, you are forgetting about the $40 of unused material that James still has if you bought this chair from Li Zhao. That material can be used to serve other needs. It is wealth that was not consumed.
I didn't "forget" the materials. Materials don't just generate out of thin air. They are produced or purchased and that requires effort or spending. That effort and spending (or lack thereof) is accounted for in my examples.
If you want to build into the assumptions that James has $40 of free materials lying around it doesn't change the math.
Secondly, the $10 I saved will be spent on something else. So in addition to the chair and James' unused materials, I can also buy $10 more worth of other goods someplace else. Let's say a haircut. Now I have a chair and a nice haircut and James still has his materials to sell elsewhere. And my barber has one more client that day.
Ok. So you saved $10 that will be spent on something else (for your benefit we can assume its spent in America and not again on foreign trade). As a group, the nation still exported $60 dollars to a foreign economy that you're not accounting for.
Finally, there's the case of what Li needs to do to make his FRN's worth anything. He needs to circulate them back to the US.
Perhaps you can elaborate because I don't see where Li "needs" to do anything. He has money he didn't before and he can choose where to spend it.
So, for $70 I have a chair and a haircut, James still has his materials, my barber Jim is gainfully employed and Li has an incentive to turn his FRN's into usable goods or services.
If I bought from James, I'd have a chair and James would have $20 for his labor and $10 to spend elsewhere, but his materials are gone.
I know this is a simplistic analogy, but the math still works out.
Your math is still wrong cus your haircuts can be applied to the other side of the equation as well:
If you buy the chair for $60 from China:
1) America gains a chair
2) America loses $60
3) America gains a $10 haircut
4) America loses the human effort to do the haircut (valued at $10)
If you buy the chair for $70 assembled in America but using materials from Zimbabwe:
1) America gains a chair
2) America loses the human effort to assemble the chair (valued at $20)
3) America loses $40 from purchasing materials from Zimbabwe
4) James spends his $10 profit on a haircut
5) The laborers spend their $20 income on haircuts
6) America loses the human effort to do the haircuts (valued at $30)
Either way, you are losing $60 in net value. The difference however, is that if you buy the chair from America, you are supporting $50 worth of local industry versus $10 worth of local industry in your example.
If we were to change the above example so that the $40 in materials were American made, then buying the chair from America would result in supporting $70 ($140 if you count everyone's haircuts) worth of local industry versus $10 in your example.
