I'm yet to see a holistic review of housing. Yes corporate ownership is bad, I think, however the availability of land is also a problem, the cost of building, which is driven by the cost of materials and labour. Arbitrarily capping one part of the problem I have doubts will help overall, and possibly make the situation worse. Eg if we block wall Street investment, and could that money go into other areas and increase competition for materials and labour and make it harder and more expensive to build homes?
