Then why do we get larger and larger trade deficits?
Within the current timeframe it's mostly due to Clinton's overly strong dollar. But the economy can take decades to reach equilibrium, and it's still recovering from the Bretton Woods era (early 1940's to early 1970's) when the dollar and imports and exports were artificially held flat. People put too much emphasis on imports and exports. A far better focus is on GDP and productivity growth.
A trade deficit is nothing more than an investment surplus. If you really want to get rid of the trade deficit, just change the interest rate and exchange rate environment downwards.
A trade deficit also really tells you that we produce high valued goods much of the rest of the world can't afford, while they produce low valued goods almost anyone can buy anywhere.
Or look at the investment picture.
Foreign countries and foreign based companies outsource to the US things like automobile factories, steel finishing, chemical plants, pharmaceutical plants, the education of their best and brightest, etc.
We outsoure telemarketing call centers, cheap toy factories, apparel sweat shops, computer programming drudge work, etc.
Frankly, it sounds like a fair trade to me.
