Being self sufficient in manufacturing is sound economics.

[Alberta's Child]

It might be sound for other reasons, but I don't think there is any economic basis to make that case.

And we already know the U.S. couldn't be "self sufficient" in manufacturing anyway. Our industrial output includes a lot of things -- like cars, for example -- that rely on raw materials that are imported simply because they aren't available in North America.
