For governments with access to today’s extremely low – and often negative – real interest rates, it may seem like a no-brainer to borrow and invest more in projects with long-term benefits. Doing so would strengthen their balance sheets, crowd in the private sector, and generate employment.
如果政府能够获得今天的极低（并且常常为负）的实际利率，借钱投资更多的能带来长期收益的项目似乎是不言自明的选择。这样做能强化它们的资产负债表，引来私人部门，并增加就业。但资产负债表算术很少成为政治争论的焦点。
