Rent control creates slums.
That is the object.
Create situations where there are ‘victims’ that need politicians ‘help’.
The more ‘victims’, the more votes.
Renters outnumber landowners, so there are more voters that need ‘help’ than landowners......
To go along with what Red Badger said - ask your Rent Controlling politician to create a non-voidable Law establishing that Taxes will be collected under those same Rules.
I can hear it now — “WE can’t do THAT - that’s DIFFERENT !!”
