False, I recommend Ha-Joon Chang's writing on this subject. The US did not develop in a climate of trade openness, it used tariffs to protect its development. In fact no developed economy developed this way, all of them protected their industry until it was mature and ready to compete, had their governments invest in research and infrastructure and so on. If you have an example of a country that successfully developed through export led development and trade openness I would love to hear it.
