ROFLMAO! Unwilling? Utter nonsense. Unable is more like it. We owe lots of money to China, and they continue to buy our debt. If they quit buying, the rates go up - and our economy is too fragile to endure increased interest rates. They can bring us to heel just by not lending us more money.
We would be wise to learn to tug our forelocks, look down at the ground, and say "Yessir, Massa" to our new Chinese overlords.
The free traders can be proud of the chains of slavery they've wrought for all of us to wear! Perhaps they can even arrange for their sons to become valued eunuchs to a wealthy Chinese merchant.
The debt card IMHO is a running joke in my book.
