How rich people make money in poorer countries?
I have this Geography homework on how rich people make money from poorer people and why they move to poorer countries like Buenos Aires etc... I know that they have the poorer people working on really low wages and I can think of other things but they are more like drug dealing etc. The homework is me advertising my country for richer people to come and make money from the poorer country. I would like some other ideas please on how richer people make money in poorer places and poorer people. Thanks!

In my experience, the wealthy relocate to 'poor' countries for the fine living. It is a little known fact that countries such as Chad and New Guiny have a widely wealthy populace. The countries are also crime free and there is no poverty.

Entrepreneurs move away from places like America because of the burdensome personal and corporate tax rates, over-regulation and constant meddling by the feds. If you want them to move back, bringing their companies and jobs with them, you'll need to address those concerns.
