There is a difference between being against this as a policy and being against it as a political reaction. Policy wise: Is there a reason to ensure that there is a strong steel manufacturing base in the country, absolutely. What you do to ensure that happens is critical. Harris and Bidem created an environment that does not allow for a steel manufacturing company to thrive in America. Based on that environment the company was sold and after thoae facts were enshrined Harris and Biden came out against the same that they themselves made inevitable.
You’re conflating a “strong steel manufacturing base” with ownership domicile.
The Daimler Benz workers in South Carolina couldn’t give a tinker’s damn whether their wages come from Stuttgart, Detroit, or Timbuktu.
(By the way, domestic steel production has increased 50% in the past 15 years.)
