A major reason for US prosperity and world-class science and technologies is the immigration of best minds from all over the world.<p>Within 12-20 years, China's real GDP will overtake the US, assuming that China's GDP grows at an annual rate 2.5+% faster than the US for the period. This is quite plausible given that the current per capita income of China is only 1/7 of the US and its major focus on R&D. Even now, many of the best Chinese graduates from US universities are returning to China to pursue better opportunities there.<p>China is spending $409 billion (PPP) on R&D, the second highest in the world after the US and ahead of the EU. This amounts to 2.1% of GDP and very high for their stage of economic development [1]. Their goal, from a variety of sources, is to overtake the US as world's no. 1 and reclaim their historical place.<p>If you look at PISA, China and the rest of East Asia, together with Singapore, consistently perform at or near the top in math and science, and quite well at reading. Even the best performing US state, Massachusetts, is significantly below those in Math and Science [2].<p>Relatedly, China is catching up to the US in AI. [3] Most groundbreaking research is still conducted in the Western hemisphere, but East Asia is getting there despite much later starts. Also, many top researchers in Western labs are from East Asia, who may later decide to move back once the circumstances change.<p>Given the above factors, and only one-fourth the population (330 vs 1390 million), if/when the US cannot take advantage of best minds from these and other countries, would it be able to maintain the technological lead for long?<p>If the answer is no, how about the military and diplomatic dominance, which almost always follows economic and technological leads?<p>A possibility: If a larger portion of the GOP wakes up to the above, possibly within the next 10 years, they will start to actively recruit high-skilled immigrants, perhaps with some sort of point-based system as in Canada and Australia. Whether it would be too late or not remains to be seen.<p>[1] <a href="https://en.wikipedia.org/wiki/List_of_countries_by_research_and_development_spending" rel="nofollow">https://en.wikipedia.org/wiki/List_of_countries_by_research_...</a><p>[2] <a href="https://en.wikipedia.org/wiki/Programme_for_International_Student_Assessment" rel="nofollow">https://en.wikipedia.org/wiki/Programme_for_International_St...</a><p>[3] <a href="https://www.nytimes.com/2017/05/27/technology/china-us-ai-artificial-intelligence.html" rel="nofollow">https://www.nytimes.com/2017/05/27/technology/china-us-ai-ar...</a>
