Tariffs remove that barrier to American industries; and let's not forget, we are concerned about American industries, not international industries. If we cannot agree on that, we have nothing more to say. American businesses should be American first, last and always.
Barring corruption, tariffs are not set up in favor of a specific business, they are intended to aid the entire industry.
Barriers gone; competition exists. Maybe a dude starts a business in his garage, maybe he doesn't. The point is, there is currently no way he can.
Thank God our business leaders and Congress people are above corruption!
