Part of the problem is government regulation. In some places, it's almost impossible to build new houses due to regulations.
Some portion of the population wants to see house prices continue to increase and they will vote for politicians who will implement policies which will support that agenda.
Of course this happens at the expense of another, also large portion of the population who do not own a house and have to pay higher rents.
I think we have a situation where part of the population is literally voting to appropriate wealth from another part of the population.
Voting for more immigration which drives up demand for houses and voting for more regulations which constrain the supply of housing.
At the same time, those people who do not own a house are wising up to the scheme and so they increasingly refuse to work or provide value to society.
Instead, they resort to their own financial schemes, illegal activity, freeloading government benefits; they've checked out from the system.
Even those who would like to contribute increasingly find that they can't due to government regulations and their inability to amass enough capital to get started on their venture.
It seems that we are headed for an economic and political disaster. The government should not allow itself to be weaponized against part of the population for the benefit of another.
The other problem is related to the role of debt in modern society. It doesn't make sense that modern banking is centered around mortgages. The point of debt was to finance new business ventures to create economic value to empower people to provide as much value as possible; not to prop up massive financial schemes which jeopardize people's ability to keep a roof over their heads.
