It is easy for government to implement housing scheme to encourage one person one house. The real problem is developers won't like it because how to earn big money like Li Ka Sing otherwise? Developers want scarcity so that they can sell more and more expensive house at smaller and smaller size. That's how tons loads of money is made.

The requirement on private housing developers to build at least 30 per cent of affordable housing in mega housing projects has been imposed since 1981. But many people complain they cannot get house. Why that happens no one know.

What is the definition of "afforable housing"? 100K or less? 300K or less?

Who bought up those 30%? The developers only need to ensure 30% are created but there is no requirements on qualifying buyers?
