Tarrifs? good idea or bad idea?

Jessizu • I wear lots of hats.

As we know this week the trump campaign has stack tariffs on imported gets from Canada Mexico and the EU.. Is this nationalist approach a good approach to our economy or will this just make things more expensive for us in the United States? This seems to be a ploy to help out trump's fellow steel friends and doesn't seem to care about the cost to American pockets
