What is the difference between poverty in the developing world and in developed regions, such as Hong Kong?

Not at all.

Thank you so much for the kind assistance.

Poverty in the developing world is more associated with the underdevelopment of industrial capitalism. In contrast, the new poverty in advanced cities is induced by developing a new phase of capitalism that goes beyond industrial capitalism and emphasizes the role of knowledge, information, global networks and global finance for capital accumulation and profit generation.
