... The current incarnation of the housing crisis has exposed our past failures to get it right and with an ever growing and aging population, the next path that is taken must be one that not only meets our current shortage but will also provide homes for generations to come.
To achieve this, house builders and developers must have access to land. The introduction of land taxation will provide this and meet the long term problems of supply once and for all.
