Like jobs, queues/lines and other various things I have a philosophy that this is because vacancies get smaller and push the market costs up as people actively move or switch. If people decide not to switch their job or leave their apartment suddenly there are more demand and vacancies. Basically the constant shuffling of where people live or work significantly create artificial unavailability. For example it takes months for an apartment to be re-occuppied. One month to clean and move. One month to find a new tenant. Jobs are no different. This is why businesses sometimes over hire and then do mass layoffs. If both adequately were fulfilled we wouldn't see any issues and apartments could opperate at a tenable rate which benefit both complex and tenant. However because the demand in the jobs would increase since no artificial un/availability will be made the pay will grow in the more in-demand roles not fulfilled. When the jobs demand rises and the pay rises this cycle will start again. It is why businesses should try to retain talent so this process doesn't repeat and cause an economic collapse due to the rising cost of rent and living. Being tenable is important.
