Which homes? The ones that are already in short supply? The ones that are currently being rented out? Would that mean nationalizing those buildings? Or are we building new homes? How are we paying for any of this? Raise taxes? Cut some other services?
None of this is simple when it comes down to the details on how to actually implement it.
My first response was: "I'd be willing to watch any video proof for or against that assumption." I think it may be time to re-evaluate my standards a bit.
