What would things look like if we took that out of the economy?
What would things look like if we produced domestically a significant amount of the $2.75 trillion in imported goods and services?
Interesting question. Among other things our overall standard of living would be lower because we would be spending more for the same goods than we do now, and the people who today produce the $2T in exports would be out of work because it's folly to think we can continue to export if we block imports.
