The chapter argues that wealth, especially its unequal distribution, is a problem for meeting the United Nations Sustainable Development Goals. It discusses cities as the places of wealth generation but without the means of considering how that wealth might be distributed to create a fairer and more equal society for all. The chapter focuses on mapping the SDGs to gain a closer look at their structure, the nature of their goals, and their relationship to economic, political, environmental or technological concerns. The analysis of the SDGs highlights that the fulfilment of many of them seems to rely on wealth creation without the fundamental concomitant of wealth redistribution. The chapter concludes by discussing how developing a sustainable built environment means thinking beyond the iconic buildings created by wealth that often only serve the few, to what can benefit everyone. The built environment forms the case study for discussing wealth for the remainder of the book.
