The need then will be for more spending on education and training – the only thing that in the long run will make American workers more productive and reduce income inequality. Similarly, the United States needs more productivity-enhancing infrastructure – roads, bridges, and ports – and not frills such as high-speed trains between Sacramento and San Diego.
按照老派的做法，扩大公共开支以扩张总需求的阶段，即使还未过去，也快走到头了。现在需要考虑扩大教育和培训方面的支出了，毕竟从长期来看，那才是提高美国劳动生产率和缩小收入差距的根本办法。还有，美国也需要投入更多资金在那些有利于提高生产率的基础设施上头，比如道路、桥梁和港口，而不是投入那些华而不实的项目，比如萨克拉门托和圣迭戈之间的告诉铁路。
