I hope by now the government realize that it is impossible to achieve a gradual appreciation of property prices. If you let the market decides, you must accept that Mr. Market is forever a manic-depressive character. And it would threaten to make us bipolar as well!
Just as a steel bar becomes permanently magnetized when exposed to a magnet for too long, the same could happen to voters. The risk is that they will vote not vote rationally.
Come to think of it, if you are rational, you are likely to be less supportive of this government these days isn't it? Or am I manic-depressive already?
