The problem is not just zoning. A boarding house simply doesn't generate noticeable income compared to standard residential housing, and with exploding land prices it simply makes no sense financially to cater to poor people.
If only there were some sort of organization that didn't need make a profit and wasn't "run like a business". One that everyone gave money to, for the benefit of all society, to make things better all, but especially for the lowest on the totem pole. If only such an organization existed! It could be in charge of governing the people, and the people could choose who runs it with some sort of choosen-ing procedure.
