Moreover, the hundreds of millions of low-cost workers who joined the global labor force when China, India, and Eastern Europe opened their economies are still putting pressure on the wages of all but the most skilled workers in the advanced economies. As the Nobel laureate economist Paul Samuelson observed in 1948, international trade leads to factor-price equalization, with wages, adjusted for skill levels, equilibrating across countries.
此外，中国、印度和东欧经济开放后，数亿低成本工人加入全球劳动力大军，迄今仍在给发达经济体的工人（技能极高者除外）工资造成压力。诺贝尔经济学奖获得者萨缪尔逊（Paul Samuelson）在1948年观察到，国际贸易导致因素价格趋同，不同国家经技能水平调整的工资趋于均衡。
