>Artificial barrier: Something arbitrary synthesized by a party not involved in an A<->B transaction.

Yes, other than:

* Being responsible for the welfare of A and B.

* Being responsible for mediating any disputes between A and B regarding their transaction.

* Being responsible for cracking down on potential fraudulent activity between A and B.

* Providing the medium whereby A and B can discharge their debts.

The government has nothing to do with the transactions. Absolutely nothing.

>Does allowing a company from California hire someone from New York 'drive down wages hurt everyone except the top 1%"? If not why does it suddenly 'drive down wages hurt everyone except the top 1%" when you change New York to India?

Because they're capitalizing on India's relative poverty.
