Goods AND services, not just goods. The OP emphasis on manufacturing is overdone. Services get a bad name among the uninformed (a nation of hamburger flippers) but services include high paying jobs such as engineering, architecture, economic consulting, finance, investment banking, information technology, petroleum engineering, etc, etc.
Natural resources are not all they are cracked up to be. Look at South Africa. Look at Russia. Look at many middle eastern nations. On the other side, consider resource poor nations such as Germany (mentioned above) but also Japan, Korea, Taiwan. Human capital and innovation drive many economies, and both goods and services are "real" outputs.
And, yes, there is another service sometimes discussed in these parts of the internet that is fairly lucrative, at least on an hourly basis...
The OP mentions trade. We do import more goods than we export. You might find it interesting to know that we export more services than we import. In July 2011 our exports of goods was $126.9 billion, our exports of services was $51.1 billion. (Imports of goods was $187.5 B, imports of services $35.3B).
As to "why you are wrong" it is difficult to know where to begin or how to respond to the statements in your OP. I suggest you begin with a few economics classes. U.T. has an excellent economics faculty; you might consider giving them a chance.
