Tap Dancing to Work: Warren Buffett on Practically Everything, 1966-2013

U.S.? Simply put, after World War II and up until the early 1970s we operated in the industrious Thriftville style, regularly selling more abroad than we purchased. We concurrently invested our surplus abroad, with the result that our net investment—that is, our holdings of foreign assets less foreign holdings of U.S. assets—increased (under methodology, since revised, that the government was then using) from $37 billion in 1950 to $68 billion in 1970. In those days, to sum up, our country’s “net worth,” viewed in totality, consisted of all the wealth within our borders plus a modest portion of the wealth in the rest of the world. Additionally, because the U.S. was in a net ownership position with respect to the rest of the world, we realized net investment income that, piled on top of our trade surplus, became a second source of investable funds. Our fiscal situation was thus similar to that of an individual who was both saving some of his salary and reinvesting the dividends from his existing nest egg. In the late 1970s the trade situation reversed, producing deficits that initially ran about 1% of GDP. That was hardly serious, particularly because net investment income remained positive. Indeed, with the power of compound interest working for us, our net ownership balance hit its high in 1980 at $360 billion. Since then, however, it’s been all downhill, with the pace of decline rapidly accelerating in the past five years. Our annual trade deficit now exceeds 4% of GDP. ...
