This is a huge, huge ballooning problem, and it will not be satisfied by simply attempting to deal with it on the supply side. We have to deal with the fact that, again, these economic theories, of the rational man or otherwise, effectively, mean that all sensible people who were simply looking to increase their self-interest and realise greater gains out of the market would, of course, be investing in housing. It simply makes sense at the moment. So the question then becomes: why have we taken off the table and labelled as too much of a political hot potato one of the things that experts across the board are calling for, and that is a sensible conversation about taxation in this country?
