I have a trade deficit with my local grocery store. Does that mean I'm being taken advantage of?
Imagine a small country rich in raw materials but whose people are otherwise poor. They export tons of valuable minerals to the U.S. but the profits are kept by an elite few who spend most of their time outside the country, and nobody inside the country has enough wealth to buy goods from the U.S. The U.S. would have a large trade deficit with that country, but would be benefiting enormously from the relationship. In this scenario, the country's people are certainly being taken advantage of, but the U.S. is absolutely not.
That's the problem with the trade deficit: it tells you almost nothing on its own. You can manufacture scenarios between countries involving a huge trade deficit, surplus, or an even balance, but where trade is fair, or where either country is taking advantage of the other. It's just not a useful number on its own.
