The beauty of it all is this:
Every nation on earth had pretty much the same starting point of hunters and gatherers that spread over the globe tens of thousands of years ago. Everyone started from the same basic foundation and a few places developed quicker than others.
My assumption is that competition over limited resources, harsh climates and a few other factors (such as noisy neighbors, from which to steal inventions and ideas) created some sort of evolutionary thunderdome, that caused an arms-race amongst an insanely big area with hotspots all across Europe, the northern parts of Africa, Arabia and up to China and Japan. These places ended up on top of the stack. The Europeans, in particular, were apparently really good in coming up with new and exciting ways to fuck up other people and how to effectively rule over huge areas unopposed. This isn't just a matter of having access to (say) steel, it's also a matter of administration, communication methods and so on.
Nothing ever prevented the Natives from doing the same in their neck of the woods, they could have created an equally advanced civilization as their European or Asian counterparts. Just to let this sink in: China, Egypt, Greece, Rome... just to name a few, these states were insanely developed "nations" (for lack of a better term) with a very nifty administrative system, and cutting edge technology and sciences thousands of years before the Natives in Northern America came face to face with European settlers. And by that time, the Natives hadn't yet even figured out how to use metals. Maybe they'd figure out using metals some time later than Europe and progressed at a slower pace towards using similar stuff, maybe coming up with similar technologies and so on, but they didn't.
They had the same chance everybody else got and there was just not enough drive or reason to invent new stuff. Even with unlimited time on a completely remote and seperated place of their own, I doubt they'd catch up. By the time, these Natives would figure out how to make monosteel, everybody else would already be building airplanes from industrially produced space alloys and aluminium.
