What changed? Mostly a shift toward neoliberal policies in the '70s and '80s that framed government intervention as inefficient and market solutions as inherently superior. We offloaded housing policy to private developers and then acted shocked when affordability cratered.
We don’t need to reinvent anything—we just need the political will to do what we already did once, and quite successfully.
Instead of addressing systemic issues like housing, wages, climate change and healthcare, we started screaming about the culture wars (thanks Reagan). It was easier (and more profitable) to stir outrage over symbolic issues than to solve material problems. We could’ve been building homes, but we got tricked into yelling about bathrooms and book bans instead.
