Perhaps the words of Lee Kuan Yew can shed some light on the matter for you. He was a prime minister of Singapore for 3 decades and lead the country from extreme poverty to a 1st world economy.<p>&quot;October, 1985. […] During my official visit, I was given the honour of addressing a joint session of the US Congress. […] I spoke on an issue then at the top of the American agenda - protectionism to safeguard jobs and check growing US trade deficits with newly emerging economies of East Asia. In 20 minutes, I described how the issue of free trade was really the question of war or peace for the world.<p>Nations wax and wane. I argued that if a nation on the rise, with an excess of energy, was not allowed to export its goods and services, its only alternative would be to expand and capture territory, incorporate the population and integrate it to make for a bigger economic unit.<p>That was why nations had empire which they controlled as one trading bloc. It was a time-honoured way for growth. The world had moved away from that after the end of World War II in 1945. GATT, the IMF, the World Bank and new rules made possible a prosperous and dynamic Germany in spite of large numbers of Germans returning from the East into a shrunken land area<p>So also with the Japanese, who had to leave Korea, China, Taiwan and Southeast Asia and be packed into a few Japanese islands. The Germans and the Japanese were able to stay within their boundaries and grow through trade and investments. They cooperated and competed with other nations and were able to prosper and flourish without wars.<p>But if trade in goods and services was blocked, then China would revert to its historical solution of small warring states conquering one another to gain control of more territory and people until they become one colossal continental empire. This tight, logical exposition may have convinced the legislators intellectually, but many found it emotionally difficult to accept.&quot;
