There is a well-established technique in detective work known as taking backbearings. Starting from where the body ends up, factoring in the wind and currents, you can work back to where it went into the water.
The same thing applies to the intelligence world. By watching what the opposition says and does and – equally if not more important – does not say or do, it is sometimes possible to work out what they know or do not know about you.
It is a like working backwards from the conclusion through the thinking process to the initial proposition.
The same technique can be applied to various aspects of our political life.
For example, when Donald Tsang was Chief Executive with Michael Suen as his housing tsar, they decided to scrap the Home Ownership Scheme and abolish the annual land sales programme . In place of the latter, we had an application list system which effectively put the big property developers in charge of land disposal.
Thinking backwards from those policy outcomes, obviously the pair had decided that Hong Kong had a surplus of residential accommodation and the percentage of home ownership was sufficient (or even too high). How else to explain the measures they took to tackle the situation?
In the same vein, property magnate "Uncle Four" Lee Shau Kee has obviously concluded that Hong Kong apartments are too spacious. How do we know this? Because he has come up with the idea of building large numbers of flats of around 28 square metres.
The Housing Society is said to be playing with the idea. Let’s hope they hold the meeting in a conference room of the same size so they can experience what is being proposed.
That is by no means the end of the ridiculous ideas being floated.
In the urban areas, it is being suggested that existing public housing estates are insufficiently densely developed. If we use every last scrap of open space within the estate boundary, we might be able to squeeze in a few more blocks. Of course 10 years later when we have experienced a sharp increase in juvenile delinquency and general depression, we will have to cope with the social problems arising.
But there won’t be any spare sites to build the community facilities we will then need to cope. All that land is also proposed for housing development.
If you think the situation in the urban areas is bad, wait until you hear the Looney Tunes coming up for the New Territories. We all know – even the Development Minister now knows – that Hong Kong’s land is about 70% rural of which something over half – a little more than 40% -- is country parks.
Putting together several different sources, we can deduce that the conclusions some people have reached are broadly as follows: Hong Kong people don’t like outdoor exercise and there is no evidence of interest in hiking; container storage and car repair are ideal activities in rural areas; some residents are still living in the 19th century under Imperial Chinese rule; we have too many well maintained recreation facilities.
We know all these things by taking backbearings. The Pandora’s Box of country park development has been opened, the "right" of some citizens to have a 190 square metre home must be preserved at all costs and we should concrete over a world class golf course to show our disdain for the rich.
If we are really serious about improving the living conditions of Hong Kong people, we should pause for a moment and think clearly about what kind of society we want to be living in over the longer term.
While it may not be possible soon, or even ever, to thin out the density of the existing urban areas, we should certainly not be seeking to cram even more people into them.
We should be building bigger apartments rather than tinier ones – nothing less than 50 square meters saleable area and even that would be much smaller than our comparator city Singapore.
We should fight like hell to defend every square inch of our glorious country parks and expand them wherever we can. They are the green lung, the breathing space that makes life in our city bearable.
We should recognise that the days of agriculture outside country parks are over, resume the land concerned and develop a series of smaller new towns. Keep the three Fanling golf courses but make at least one of them a public one.
And finally we should consign the small house policy to the dustbin of history.
Now that is the basis of a housing strategy worthy of the name.
