The hole in your sarcastic premise, is the fact that the US was once a developing nation, dealing with vastly more powerful colonial powers. It was the colonial powers and their capital that provided the seed capital for the US to become what it is. Just as China was / has been a developing nation and is graduating from that status, built up by foreign developed nation capital. Just as South Korea, Australia, New Zea…
Wow, what a wonderful idea. Let me just roll my sleeves and create a successful nation. Germans, Czech, etc. were obviously so much smarter and hard-working than us - that's exactly the reason why they created a successful nation. I have no words.
I said, directly and indirectly, that developing nations benefit immensely more from developed nations than vice versa. It was similarly true for the US as well when it was a developing nation. It's factually true and very easily demonstrated: it's why the global median standard of living is at the highest it has ever been, famines are almost non-existent globally, the median life expectancy globally continues to expand, there is less extreme poverty today than at any other time in recorded history, global equality is at an all-time high and has continued to improve, food security is at an all-time high, infant mortality is at an all-time low, etc.
If you were right, none of that could be true, because all the wealthy & powerful nations would be busy oppressing all the poor nations, such that they could never climb the standard of living tiers.
Over five decades Vietnam suffered repeated occupation, genocide, famine, civil war, a brutal form of Communism, and overall had a large percentage of its population killed. Today they're on a booming express train toward a middle income economy. What excuse could you possibly present next to that? Countries like Vietnam (and China before it), or Czech, or Estonia, demonstrate very clearly what's possible and they deserve credit for their accomplishments.
