I remember an interview made to El Ché Gevara where he was told that the Capitalist countries had less poor people than the Communists like Cuba.
He answered that was true, but unfair because Capitalist countries are slaving other countries to sustain their economic model and they need other countries to have poor people.
That's the fucking point almost always.
The problems are not tackled from the global point of view and purposed solutions are often not sufficient.
