- Cities across the world built thorough sewage systems, preventing the need for private citizens to empty their litter buckets out the window – a large river in Chicago was even reversed!

- Cities across the world built mass transit networks, enabling citizens to move around efficiently without relying solely on private vehicles.

- Cities across the world should build affordable housing networks, as Vienna did. This way, citizens don't have to fall victim to the exploitation of speculators and distortions of the supposedly fair market.

Public affordable housing is a necessary infrastructure, just like sewers and transit, to create livable cities for all residents.
