Be careful what you wish for. China also has the hukou system, which is sort of an internal passport that effectively prevents many people from moving into the popular tourist locations. Get out into the rural areas and you'll still see a lot of real poverty, although housing is cheap enough there that there aren't many homeless.
There's also a cultural factor at work. Allowing a relative to be homeless causes loss of face so family members feel more obligated to pitch in and help them out, sometimes to the extent of providing a free room. (I'm stereotyping a bit here but it's generally true.)
Countries generally have a immigration system that prevents people from moving there when you don't have enough money to support yourself.
In my experience most countries put barriers in place to prevent people from moving into the country, from another country, when you don't have enough money to support yourself, but I believe the parent is describing a system that puts barriers in place for internal migration of its citizens.
Russia has a similar system. https://en.wikipedia.org/wiki/Resident_registration_in_Russi...
