Not when 'trade' means export nothing and import everything. Like we're doing. In the modern world, national independence is extremely easy to do. We can make everything we want here - they never used to be able to do that. With scarcely few exceptions. Which isn't what I'm saying we should do anyway; I'm saying we need to make it more desirable for people to hire locally, rather than outsource. Which would be easy to do by increasing taxes on imports. BUT, doing so would, at least on the short term, deal extensive damage to our market due to the sudden increase in labor costs. But over time that would ease out, and our economy would gradually become stronger.
