[+/-] Protectionism is anti-humanistic

Forbes Magazine's Steven Landsburg criticizes economic protectionism as anti-humanistic. I don't think that was his intent, but the humanistic basis of his argument is sound:

It is just plain ugly to care more about total strangers in Detroit than about total strangers in Juarez....

After all, if it's okay to enrich ourselves by denying foreigners the right to earn a living, why not enrich ourselves by invading peaceful countries and seizing their assets? Most of us don't think that's a good idea, and not just because it might backfire. We don't think it's a good idea because we believe human beings have human rights, whatever their color and wherever they live. Stealing assets is wrong, and so is stealing the right to earn a living, no matter where the victim was born.
