I'll bite on tariffs. In a vacuum, my default opinion is that tariffs impinge on individual liberties and distort economies—they are a form of government interference and should be avoided. Since we do not live in a vacuum, I imagine two scenarios in which I'm okay with import tariffs:
- Countries who don't play fair should be treated differently from countries who do. For example, if a country subsidizes their own industries to make them more competitive in the global marketplace, then other countries are justified in imposing proportionate tariffs against that country. Similarly, if a country imposes import tariffs, then other countries are justified in imposing their own proportionate tariffs against that country.
- If an industry is vital to national security, then this changes the calculus significantly. A contemporary example is energy independence from belligerent regimes. *cough* Russia *cough*
Barring these scenarios, I favor allowing the markets to determine the winners through free and fair competition.
