One of the many reasons exclusionary zoning needs to die in a fire. The urban housing crisis has been allowed to grow for decades, so we're long past any single solution, but I'm increasingly convinced no combination of fixes can succeed while exclusionary zoning still exists.

Japanese-style inclusionary zoning splits the difference nicely between making sure people don't live next to loud, potentially dangerous industry and allowing lots of mixed-use, human scale developments of varying density.
