But what are the little dynamics that cause that...
I think it is really a simple answer that people try to complicate. The trade deficit is an effect, not a cause. A booming economy in the US CAUSES a trade deficit. Why? In good times, we generate so much national product, that we can afford to let some go to other countries. In bad times, when the economy is sour, we cannot afford those other goods and the bad economy causes a reduction in the trade deficit.
People try to complicate the issue with good sounding, but hollow, arguments that the trade deficit CAUSES economic change here. The fact is, as long as we don't let the deficit get massively out of control (in either direction), the deficit doesn't cause anything.
