Rent control depresses housing supply. It subsidies current tenants with future tenants' increased cost. The high housing cost people complaining about is the cumulating cost of decades of rent control. It incentivizes tenants with artificial low rent to stay beyond what were needed. People with low rent hang on to the units even when they have bought houses (I actually know people doing it). It decentivizes landlords to keep the buildings as rentals. It decentivizes investors to add more housing supplies.
