Quote from clacy:
They are not "buying dollars". We are giving them dollars in exchange for the crap they make. Then they have a choice. They can either:
1. Sit on actual dollars in a reserve account, which make an inflation adjusted negative return
-or-
2. Buy hard assets and services with those dollars from someone who would rather trade what they have for dollars
-or-
3. Buy US treasuries
So unless you're suggesting that they no longer want to sell us the "stuff" they produce, then not much is going to change.
