This is a good example of that. Rent control tends to benefit the older generation at the expense of younger people and families. It does nothing to solve the actual problem of lack of housing inventory.
"Economists from both the left and the right have a well-established aversion to rent control, arguing that such policies ignore the message of rising prices, which is to build more housing. Studies in San Francisco and elsewhere show that price caps often prompt landlords to abandon the rental business by converting their units to owner-occupied homes. And since rent controls typically have no income threshold, they have been faulted for benefiting high-income tenants."
This is what would really help with the housing problem
"State Senator Scott Wiener, a San Francisco Democrat, offered a bill that would essentially override local zoning to allow multiple-unit housing around transit stops and in suburbs where single-family homes are considered sacrosanct. The bill was shelved in its final committee hearing this year, but Mr. Wiener has vowed to keep pushing the idea."

I'm not sure that's how rent control works. Unless I missed something, your rent is only capped if you don't move.
