China and some other countries subsidize their steel producers and sell steel cheaply, sometimes for less that it costs to produce. Then they put our producers out of business so they can jack up the prices. We need steel for vehicles and military armaments. Where are we going to get steel if all our plants are gone, our steel comes from another country, and we have a war with that country or one of its allies?
I don't mind the tariffs. If I buy a new truck or car, the price of the raw steel is only a small part of the overall cost. There are other materials, fabrication, paint, labor, overhead, transportation, etc. all contributing to the cost of the vehicle. So if the steel goes up 25%, the vehicle will cost a few percent more. Worth it to not have our country beholden to a Communist dictatorship.
Any manufacturer who has a 25% increase in raw material and uses that excuse to raise the cost of the finished product by 25% or more, is simply using the tariff to make more money. I like money, but competition will sort it out.
