To extend your grocery store example: you have a trade deficit with your grocery store, but you have a trade surplus with your employer! You’re not running a structural trade deficit, and it would be bad to do so.

Your example about small countries is irrelevant because nobody cares about the trade deficit between the U.S. and Bangladesh. Virtually the entire trade deficit is the EU, China, Japan, Vietnam, Canada, and Taiwan. The EU, Japan, and China are big, diversified economies and there is no reason we should have a trade deficit with them.
