Surely you see that these are directly connected. With an increasing cost of living and a legally fixed profitability per month that isn't going up over time nor keeping up with inflation, from the landlord's perspective, there's little to no incentive for them to fork over cash they never got from the apartment to put back into it. At that point the only incentive is to hold onto the property itself and wait for its value to increase while deducting depreciation, and perversely, they are incentivized to make you as uncomfortable as possible since they cannot raise the rent on the unit until you move.
It's my opinion that if we want rent control, there should be a cap on the amount of time that ends sooner than "on death", especially if you're not old. (For old people who are basically living in the last unit of their lives, it makes sense to me to rent-control those).
