If the average rent for an area is going up really fast, say 15% a year, and because lets say almost nobody's income is rising that fast, lets say that as a sort of act of desperation, a law gets passed by a municipality saying that no matter what rental agreements or leases say, people who rent for a month or longer are protected from arbitrary evictions and rent increases larger than the CPI, lets say that is 3.5% a year, for as long as they stay in an apartment, as long as they are a good tenant and pay rent on time and don't break laws.
However in a few years the going rate may be twice or more what long term tenants are paying.
What happens then? What is the solution? This is a real problem.
