What happened in Vienna—of course, they had a number of decades to do it—was because of the strength of the non-market sector. This has had a mitigating effect on the market sector. You can get a market rental in Vienna for about half the price of an equivalent apartment in another major European city like Rome, Paris or wherever else.
This basic strategy suggests our country should probably examine how strengthening the non-market sector also has a beneficial effect in terms of providing an alternative to the market and reducing the inflationary influences on land value.
