Higher investment in the US by both domestic and foreign companies would boost economic growth, while the resulting increase in capital –&#160;new businesses, factories, equipment, and research –would improve productivity. That should, in turn, boost real wages over time (although the link between productivity growth and wage growth has weakened during the last two decades).
国内外公司均增加在美投资能够刺激经济增长，与此同时，由此带来的资本增加——新企业、工厂、设备和研究——能够改善生产率。假以时日，这反过来能够提振真实工资（尽管生产率增长和工资增长的关系在过去二十年中有所减弱）。
