[The public debt] does not have to be repaid, and in practice it will never be repaid.That's the economics of reality, as opposed that of the textbooks. Quote from that article:
,,, foreigners do us a favor by buying our bonds. To acquire them, China must export goods to us, not offset by equivalent imports. That is a cost to China. It's a cost Beijing is prepared to pay, for its own reasons: export industries promote learning, technology transfer and product quality improvement, and they provide jobs to migrants from the countryside. But that's China's business.That concept is exactly the title of this blog!
For China, the bonds themselves are a sterile hoard. There is almost nothing that Beijing can do with them. China already imports all the commodities and machinery and aircraft it can use--if it wanted more, it would buy them now. So unless China changes its export policy, its stock of T bonds will just go on growing. And we will pay interest on it, not with real effort but by typing numbers into computers. There is no burden associated with this, not now and not later.
