> Similarly, if we allow illegal immigrants to rent flats then that will also push rents higher. Should we attempt to prevent this as well? If not, why not?
There are lots of factors that impact housing supply and demand. Whether they should be regulated / stopped generally becomes a question once the public actively engages in discussing it (see foreign investment in the Pacific Northwest for an example).
Basically, if the public doesn't care, the politicians don't care. Since a pol's main incentive is to get re-elected, the issue has to become important to their constituents, otherwise it effectively doesn't matter.
