Christian73 saidIf a company or industry was seen as a threat to the stability of the US, the federal government could seize or nationalize it to prevent harm coming to the country.
Sure. Just like the Democrats, if they are in control of the Presidency and the Congress, can have all Japanese-Americans rounded up and sent to internment camps (again).
That doesn't make the action Constitutional.
Now, where in the Constitution does it say the Federal government can nationalize a company that is "a threat to the stability of the US."
(And don't cite "Necessary and Proper" please)
SouthBeach - You don't understand the Constitution in a meaningful way, nor the 230+ years of constitutional jurisprudence that has followed its establishment. There are lots of Constitutional acts of government that are not "spelled out" in the Constitution because the founders meant for it to be a living document that guided the country, not a rote set of rules.
In this instance, the case most applicable is Youngstown Sheet & Tube Co. v. Sawyer
, wherein the Supreme Court found that while President Eisenhower could not through executive order nationalize a company, Congress could pass legislation to effect same.
