Severely taxing imported steel would force our steel production to go up. Now, if only we did that with oil!!! We have more oil in reserve than any other Country. And we are sitting on it. Why?
And the cost to the steel buyer. Us steel producers can now freely raise their prices 24% compared to the lowest foreign price and still be cheaper. The result is higher prices to the initial business and final recipient of any product that includes steel as component or steel as the final product. That is only the beginning of the economic ramifications.
I'd say we aren't sitting on it (oil), demand has driven up the costs for crude, there is a lag between extraction and refinement. The higher cost is associated with the current demand and refining capabilities. The free market. My opinion, I welcome opposing views.
We have no control over the OPEC countries, but I noticed Saudi Arabia has responded to the President's call to increase their extraction of crude. There will still be a lag on when the crude enters the market as refined gas, and prices will reflect that. Higher fuel prices are a result of growing economic conditions and consumption (to the exclusion of California).
