Earlier quoted context omitted.
It hasn't entirely stopped rents in HK being untenably high, for many people. It has rent controls, but the system permits some very untenable outcomes which if left unchecked would re-create Kowloon Walled City. So whilst politically I agree, practically I am unsure there is no land speculation: A waterfront view remains valuable in and of itself, no matter what.
Right, obviously HK is a bit of a special case. Land in Manhattan would, I'm 100% certain, remain incredibly expensive. The cool thing about leases is that you can change the cost of the lease periodically, which ensures that the value of the land does not accrue purely to the person occupying it.
Reminds me of the old macro economist joke: There are 4 types of economies, developed economy, developing economy, Japan, and Argentina. Maybe HK should be added to that joke...
