The so-called 'housing crisis'

So… we need to build more houses, ever more houses; and still a very large number of people occupy a single house that once housed a whole family just one generation ago…  No I think we should all learn lessons in getting on with each other; less divorces, less separation and less cranky behaviour as we all love our own privacy, company far to much and find every reason not to co-habit and share. Then our housing stock would have more of a chance of sufficing... Job Done!
