The more factories and machines a country has, and the more it replaces older factories and machines with more up-to-date models, the more productive its labor force is. The more houses it builds, the better the private lives of its citizens.
但新兴经济存在投资过多的问题吗？难道投资不是意味着人民生活的改善？一个国家的工厂和机器越多，替代老旧厂房和机器的现代化设备越多，也就意味着生产效率越高。建设的房屋越多，人民的生活就越富裕。
