This just isn't true. Rents decreased in Texas after an increase in supply. Increasing supply will decrease prices. Freeways typically don't cost money so that doesn't apply.
Rent control just rewards people who are lucky enough to get locked in lower rates. The best way to make rent affordable is to increase supply, then the price will fall.
Criminal penalties for the landlords and at least triple refunds issued to affected tenants. Also build so many new apartments that the prices fall since landlords are forced to compete to find tenants.
