Global middle class is expanding, and millions of people are being lifted out of poverty. The bad news: wealth inequality within countries, in both the industrialized and developing worlds, is actually worsening. Meanwhile many people (23 million in 2017 alone) are already being displaced by natural catastrophes aggravated by the effects of climate change. While a number of public-private partnerships have been formed to tackle these issues, more must be done to restructure development finance in such a way that makes it more attractive to a wider array of investors. Excluding people from the benefits of economic growth can undermine the sustainability of that growth – and failing to address serious environmental issues, like threats to biodiversity and natural resources, is a formula for disaster.
