But that’s where the social housing is supposed to come in. It’s the failure of government to build that that’s the problem.
We need government to start building masses of council housing with legal provision that it cannot be sold off.
But then a government would change the law to allow it to be sold off for short term gain without any care for the long term cost. Because that's what our political system is geared for.
The only social housing system I can think of that actually works as intended is a freak setup that essentially works on the basis of nothing more than tradition and honour - the Fuggerei. Set up ~500 years ago by Jakob Fugger, who had become immensely rich and decided to spend a small part of their vast fortune on doing something beneficial to their home city. Some decent quality housing at a low rent with a promise that the rent wouldn't be increased. Their descendents have continued the project ever since. And they still haven't increased the rent. It's about 75p per year. No typo. Jakob Fugger funded a trust fund to support the project and his descendents have done a good job of managing it since then. But that's not a viable model for housing. It only exists because the Fugger family continues to choose to honour the wishes of their ancestor ~500 years ago. Businesses don't work that way and nor do governments.
I was looking at the issue of parking in Chicago last night. It was under the complete control of the mayor, effectively no restrictions. A few other people who were there to glance over the mayor's actions and rubber-stamp them. So the mayor sold parking in Chicago to a private business. Giving them a 75 year contract and imposing a 400% increased in parking price in Chicago and guaranteeing that the company would profit above inflation, absolutely guaranteed six ways from Sunday and paid for by taxes in Chicago. But not just profit from parking. Also profit from theoretical parking, parking that never actually occurs. If any future local government ever reduces parking for any reason (roadworks, cycle lane, bus lane, whatever), Chicago will still have to pay the company for the parking that didn't happen. For the full 75 years. If parking prices increase by less than inflation (let alone go down), Chicago will still have to pay the company at the agreed price of 400% of the pre-sale parking price plus inflation. If prices go up by more than inflation, the company pockets the extra.
The mayor has changed a couple of times since then. But the people of Chicago will be paying through the nose for that major's decision for the full 75 years. The major absolutely didn't get any money for themself from the deal and absolutely didn't get a well paid cushy no work involved "job" with the company after leaving office.
That's how politics works.
