@hybotics Perhaps that could work in the bigger cities in the US.
In HK, where buildable land is so scarce, it wouldn't just be about one company agreeing to build more affordable homes for a smaller profit: even if they were willing, they'd be outbid massively at land auction, amongst other roadblocks further on.
Such a project would probably need a strong majority agreement amongst landowners, building companies, and the government. Or a deviation from the capitalist free economy model that HK has long followed towards a more socialist deal…but then you might as well move to China, which has a whole lot more problems than that.
At least in this most expensive of cities, there's no winning.
