To trace the global history of the twenty-first century so far is to trace a history of growing unaffordability and shortage. After years of refusing to build sufficient housing, the entire country has a national housing crisis. After years of slashing immigration, we don't have enough workers. After decades of off-shoring manufacturing, we have a shortage of chips for cars and computers. Despite decades of being warned about the consequences of climate change, we haven't built anything close to the clean energy infrastructure we need. The crisis that's clicking into focus now has been building for decades--because we haven't been building enough.

Abundance explains that our problems today are not the results of yesteryear's villains. Rather, one generation's solutions have become the next generation's problems. Rules and regulations designed to solve the environmental problems of the 1970s often prevent urban density and green energy projects that would help solve the environmental problems of the 2020s. Laws meant to ensure that government considers the consequences of its actions in matters of education and healthcare have made it too difficult for government to act consequentially. In the last few decades, our capacity to see problems has sharpened while our ability to solve them has diminished.

Progress requires the ability to see promise rather than just peril in the creation of new ideas and projects, and an instinct to design systems and institutions that make building possible. In a book exploring how can move from a liberalism that not only protects and preserves but also builds, Klein and Thompson trace the political, economic, and cultural barriers to progress and how we can adopt a mindset directed toward abundance, and not scarcity, to overcome them.
