No country needs rent controls. They need ownership controls. As in, nobody should be able to own more than 1x primary residence and 1x holiday house &/or investment property. Period. No company should ever be allowed to own residential land/property, except for the duration of a build (with hard limits for development/build/sale that prevent artificial price controls).

Neoliberalism/conservatism have failed humanity for housing security, financial & economic security, national security, employment security, mental and physical health, education, civil liberties; the list is endless. Continuing this several-decade failure any longer is insanity.
