Overly optimistic. Try 10 years. The debt will be unsustainable in the inflation-induced spiral of interest rates. The USA will actually default, not long after our bond rating becomes junk. Will China be able to stabilize the world economy and prevent a global depression? maybe, maybe not.
Anyway, we are all destined to live in a third world country, surrounded by moldering artifacts of our glorious past. At least all those wood fires are "renewable energy". We'll still be proud members of the Middle Class.
