No-one would move, ever. People wouldn't be able to change jobs even for much higher salaries or better conditions. Children would live with their parents forever. Many people would live precariously in illegal sublets with inadequate fire exits etc. Developers would stop building. Landlords would stop doing maintenance and let their buildings rot. Everyone would be miserable.
> Many low income renters are paying 50% or more of their income on rent, that's not sustainable for the wider economy that relies on low skill labor to function, and the solution is not to have people commute 4h every day to clean an office, teach a class, or fight a fire.
Rent control creates longer commutes. To the extent that the economy actually relies on low skill labour, it can pay the actual cost of having that labour where it needs it. In fact by having rent control you artificially depress wages and encourage companies to employ humans in bad jobs rather than finding ways to make things better.
