Do they move any essential services out to places that're a pain to get to but conveniently far from where 'decent people' or 'tourists' might have to deal with them? If not they need to read up on what the NSW govt did for the 2000 Olympics (and every other time they want to pretend Sydney isn't a festering shithole).It's meaningless if those people continue existing, living, and can be seen in real life, outside of statistical charts.
Let me introduce the swiss method consisting in keeping the price of public transportations and any outside activity beyond their reach, forbidding begging in the streets, and maintaining a culture and social pressure shaming the poorer people out of sight and away of (as punishing and humiliating as possible) social services. It's not simply about making them invisible in the stats, it's also about keeping them locked inside their home (or off the streets if they don't have one). At least until their corpse's smell becomes too annoying for the neighbours.
Plus when Westerners are talking Global Poverty they're conveniently not including their own citizens living in poverty but, you know, *vague waving motion* foreigners in foreign places.
