People are driven to these places by economic opportunities. They are not living in cages because they have nothing else to do, but because they want to live in Hong Kong, even much better conditions in mainland China is of no interest to them. This is like how people abandon their well built, fully paid out 3-bedroom apartments in mainland Russia and flock to Moscow where they share rooms with strangers, with 5-10 people living together in an apartment in their 30s. This isn't poverty, this is how people try to escape poverty. They cannot be helped to do it (otherwise more people will flock in - you can't move all China/all Russia to Hong Kong/Moscow), and should not be banned from trying (that kills economic progress, with Russians staying in Russian province means they will simply slowly die of vodka, in Moscow they might do something useful, i think same goes to Chinese).
