US for almost all practical purpose for most of its existence is an extended Britain. And for the remaining part the best result of European colonialism. The US is basically Europe. There are now differences of course, but the bigger story is this.

By and large Russia and China are the result of revolutions, that were attained in the climate of what was then the dominant political and economic narrative of the time.

The fact that countries like China and Russia have done whatever they have done what it took Europe and its colonies centuries to do is in itself a huge proof of success, if you want to measure it that way.
