The idea is to drive out of business those corporations which do NOT respect theor our sovereignty. It will hurt at first, but would quickly be replaced by the 'mom and pop' shops that used to be one major of America. And THAT'S the beginning (again) of our very own industries. We can once again produce our own textiles, food, electronics, and everything we were once so proud to label "Made in America".
This is NOT "protectionism" just Common Sense.
