Generally all these issues seem to be made worse by restrictions on new housing development, land use restrictions and a large indigent population who cannot afford housing with their current wage earning ability.
For now it seems like the government’s preferred solution is to not address the root causes and let landlords slowly incur losses and wealthier renters pay through the nose. I believe governments should be doing the exact opposite, they should have landlord and development friendly laws. The alternative seems to be mass homelessness and general societal decay. No one will invest in real estate if property rights cannot be enforced. However, indigent voters are a large vote bank. In California, 60% of adults paid no income tax in 2020.
