This article explains why it's important to invest in public infrastructure to improve our lives and cities. It talks about how to keep these systems running smoothly by making smart choices about money. There is a difference between funding (how we pay for things) and financing (how we borrow money), and both are crucial. The research shows that where the money comes from and how it is managed can affect who pays for services and how much it costs. The report also discusses how funding is shifting from the government to private sources, which can impact the quality and cost of services. By understanding these choices better, we can work together to make sure everyone has access to sustainable public infrastructure.
