The reason

Singular?

things like this are produced overseas is to maximize profit collected by the companies, and secondarily to skirt environmental laws (for even higher profits).

Denmark is a hotbed of seedy corporate types getting rid off the backs of their plebe workers, then? There they go, circumventing their corrupts government’s environmental regs and wrecking waterways.

Denmark, one of the happiest countries on earth? A Nordic country in the EU, which itself is known for having lots of regs like employment and environmental obligations?

Your assertion just sounds completely absurd, even before we compare it to “at-will” work in a Red state. The only reason to keep it in Denmark is because of people, not profits.
