I suppose, for the foreseeable future, this is going to be a problem in Western [ or international ? ] societies, in general i.e. people are living in smaller 'groups '. The old situation in the U.K. of a married couple with, say, 3 children, living in the same house, is fairly quickly, losing ground.
With that trend, plus the increase in our population, the problem WILL get worse, unless some future government comes up with some radical ideas. Either that, or perhaps a few million more people will emigrate.......and leave those behind with at least a bit of a chance to have their own living space, in their little Eden ! Rule Britannia....etc.....
