Technology can provide abundance and means to a more equitable world and reducing social problems, yet politics is often driven by scarcity and regulation that undermines big ideas and reforms. Klein & Thompson argue that liberals have focused too much on boosting demand (i.e., provide transfers) and not enough on increasing supply. The authors identify serious barriers to progress and how alternative strategies can help leverage abundance and a better future. San Francisco has a homelessness problem because housing is unaffordable, but excessive regulation makes it difficult to build more and decrease costs. Regulation tends to resemble sedimentary rocks, where new layers are added but older parts rarely removed. Good intentions can undermine efforts, as when funding proposals to promote semiconductor manufacturing must consider environmental impact, equity strategies, and inclusion of minority-, veteran-, and female-owned businesses. Bypassing requirements can speed up things dramatically – the I-95 bridge in Philadelphia was rebuilt in just 12 days after a severe fire, and this met with universal political approval even if it violated legal procedures. The book discusses barriers to innovation in science and research, and how funding mechanisms could be improved to encourage bigger ideas rather than safe proposals. This book is focused on the US, but its message has much wider applicability, and its optimistic tone provides a useful approach to present challenges and the future.
