The way we build and use good housing impacts economic growth by influencing jobs, savings, investments, and how productive workers are. People have only recently started to widely accept this idea. Since 1945, experts on housing have had three different opinions about how housing affects economic growth. In the years right after World War II, most experts saw housing as a social cost and something that slowed down economic growth. A few argued that housing could be an important addition to specific development projects, especially in distant areas. Over time, housing has increasingly been seen as something that helps growth, not just because building houses is a major industry with a large ripple effect, but also because housing has social impacts that affect the economy in various ways. This history of how opinions have shifted makes us wonder why the change happened.
