I dont have any ready solution. I know that London was at this point 25 years ago, and has not really resolved it. I worked there is the 1990s and our company wanted to employ a specialist engineer. We finally found a guy in Manchester, he was delighted to work in the cutting edge area we specialised in, came to us for a month, then said sorry, but with a wife and 4 kids he had a 4 bed house and a large garden in Manchester, in London he could have afforded a 2 bed flat. We could have paid him 3 times the salary of the other engineers, but that is not the way the world works.
I think there is something quite succinct in your comment above.
Firstly, you dont have the solution - which recognises that there is a problem.
Secondly, you recognise that London arrived at this point 25yrs ago ( I suggested 15yrs ago here).
I don't proclaim to have the solution either.
But in my opinion, I recognize some factors that I believe go to the heart of the issue.
1) The housing sector has by and large been left to the private investment market.
2) The State, and successive governments, have through their policy decisions, diluted or neglected their understanding/responsibility of what housing actually is and what it is for.
The result being, over the long-term, allowing housing to be treated as a commodity to buy and sell for profit.
Housing is not a commodity and should not be treated as such. It is a fundamental necessity for the functioning of a
civil society.
So if the population has an increasing number of homeless, or if increasing numbers are in rent and mortgage arrears, then the prospect of social upheaval is increasing all the time - which is no good for anybody.
Irish history is littered with such examples of social upheaval from Land Wars, 1916, Dublin 1950's, Belfast, Derry which in no small part stemmed from the issue of housing.
But Ireland is not unique, England, Scotland, South Africa, Gaza and even the good 'ol USA.
(In fact, as a betting man, I would consider significant pockets of the US to be nothing short of a tinderbox.)
The State has shown itself in the past as being able to deliver housing for the population on a large scale.
It has shown itself to be inadequate in the management of that housing.
The private sector has shown itself as being able to deliver housing quickly and efficiently.
It has also shown itself to be inefficient and to a point, reckless - basically building anywhere it was permitted, for the ultimate purpose of profiteering and nothing else.
So the solution, if found, will emerge from policy, not free-markets alone or authoritarian State control alone.
A mixed economy I think they call it.
Both the State
and free enterprise working together ie. society, or more commonly referred, democratic socialism.
