Friend, if we did not rent out our properties there would be less to go around and rents would be higher and many may be open to risks from bad LL's just like LL's are at risk from some awful T's
As we only buy in nice areas and always rent out slightly below max prices and then dont raise the rent for as long as T's are there and if they are good, T's dont want to leave.
As time goes on, we may give away property to hard-working people on low wages that have spent their money on essentials but still cant afford a property.
HTH
