All of our aspirations for sustainable development depend on good governance. Good governance is vital so that government provides the public investments and the public services that underpin economic development, that ensure that no one is left behind, that ensure high-quality public services-- healthcare or an education or in infrastructure. We need our governments to behave, and the evidence is quite overwhelming that when governments are corrupt--and many, many are--two phenomena very powerfully show themselves. 

1. One is that corruption is adverse for economic development.
2. The second point, which is a little bit surprising perhaps but completely understandable as soon as one thinks about it, is that an individual's sense of well-being, life satisfaction, is strongly affected by the perceptions of the lawfulness or the corruption of their governments.
