Bottom line AFAIAC is we need more social housing stock. The government could easily control the prices, but it's not politically viable as the financiers won't be fed adequately.
Yep, if things continue on as it is at the moment something will have change, governments will hit the point where a larger amount of voters are not mortgage paid off/cheap houses waiting to retire. Policy will adjust to attract them, again when looking back at history mass home ownership is a relatively new concept, it's a system that has been fiddled with over the years. It will be prodded and poked in the future to achieve something else.
