"Denmark . . . has a homogenous population who . . . have a good work ethic."

I'm guessing we're getting to the heart of how you'd fix America, Ubersturmbannfurher Stevenson.  

That said, your argument betrays a childlike ignorance.  American worker productivity has increased dramatically over the last four or five decades while wages have been stagnant.  Compensation for Danish workers is about a robust union system the is integrated with, rather than trodden on, by management (and by extension, the hallmark of a functional democracy rather than the oligarchy we have in the US).  Your argument, outside the creepy racist overtones you're betraying, is simply incorrect, however much it may warm the cockles of your three sizes too small heart when you hear it playing in your echo chamber on Fox News.
