Other examples would include the protectionist legislation offered when they were getting their shit rocked by Asia the last time around, in the 70's, every time we've gone to war overseas for oil, and the CAFE standards which have generous exemptions for all the vehicles they actually make money on because no other manufacturers bother to make 3 ton trucks for suburbanites.
