Frankly, I find this entire debate staggeringly alarming. I have a laundry list of reasons I can check off, but I'll just comment on a couple of key points.
Firstly, both sides of the debate are constantly spewing misinformation about the benefits of their preferred system, the demerits of the other side's, and the causes of our current problems. No reasonable conclusions can ever be drawn as long as the people discussing the matter are mindlessly spouting party-endorsed talking points.
Secondly, it showcases the fact that the nation is in the middle of a culture war that's divided the populace into fundamentally incompatible segments who can never agree on a number of important issues. The nation's character has been splintered, so no policies, regardless of whose they are, can ever represent the interests of everyone. That's a much larger problem than any being discussed in regard to our upcoming elections, and one that will haunt us for generations to come. It's nothing short of lunacy for us to be battling over these issues instead of working to resolve these incompatibilities through any means necessary, even if the outcome is the separation of the USA into two sovereign states. Once that's been accomplished, we can work toward the betterment of society, rather than the repression/destruction of the other side. And on that day, pigs will fly on magic anvils made of butterscotch and the moon will razz a passing comet.
And another thing... why are so many people in such a rush to be just like other nations when those same nations they want to emulate have problems that equal or exceed our own? Doesn't it make much more sense, in an era where politics are evolving into such complex forms at such a rapid pace, to keep a number of different methods active in the world? As the USA tries to be more like Europe or Canada, we're robbing those people of the innovations we might devise through our methods, as well as robbing ourselves of the benefits of their systems once they've been refined or the knowledge of why they failed. But again, flying pigs and a moon raspberry.
