Economist Sung Won Sohn of Norwest Corp. in Minneapolis said Greenspan's testimony was designed in part to calm jittery international markets. Hinting too strongly of higher interest rates could have caused money to flow out of trouble markets and into U.S. securities offering a higher return. Greenspan as much as acknowledged that. But he said it would be a mistake to use political pressure to clamp down on trade with countries, such as China, with which the United States has a large deficit. Market forces will work to reduce the deficit over time, and the low U.S. unemployment rate shows that a trade deficit on its own does not destroy jobs, he said.
Systems are very unforgiving.
Software programs do not allow for a single mistake. You cannot be approximately correct.
