Oftentimes people claim that the housing crisis is a result of investors outbidding regular home buyers, not a fundamental shortage of supply. This video debunks that idea, using the city of Rotterdam – which effectively banned buy-to-let speculators across much of the city – as an example. The result actually worsened housing affordability for lower-income households and increased gentrification.

In short, there is no solving the housing crisis without simply building more housing.
