Right now in Australia we have tyranny of the majority, because the 30% of home owners + 30% of mortgage holders have realised they can get rich if the government restricts supply (bans development) and increases demand (adjusts immigration yearly to outpace construction). For a century there seemed to be a 'social contract' that getting young people a home and helping them start families was important for the country, now though that concept seems to be totally dead.
Just creating a legal 'right' to build a house on your land would be the best fix and help a lot, but long term we really need to fix the social contract which held everything together in the first place.
