I disagree. I think we should only have tariffs against countries that do not have comparable regulations to our own.

Once we do that, there is already ample incentive to manufacture domestically (saving on shipping costs).

The only places, then, who manufacture elsewhere are companies based in those countries. These companies would often sooner give up the American market than open an American plant. Since there is no moral justification for this (unlike tariffs based on level of regulation), it's just strongarming countries. It ends up being a spit in the face of American freedoms, as now they may not be able to purchase a unique German car.

The point of the tariffs is so Americans feel the actual cost of their moral legislation, and so that moral legislation actually does something. The point is not to force Americans to buy domestically. Nobody should be forced into buying from one company over the other. That's how innovation dies.
