simple economics

if poor countries become less poor 

then the populations and companies of poor countries 

will buy more products and services 

from american, european and chinese companies 

so that usa, eu and china will earn more money 

so if usa, eu and china gave more economic opportunities 

to the populations of poor countries 

to enable them to get jobs and start companies 

in those poor countries 

then that could grow the economies of those poor countries 

relatively small amounts of money is needed 

to invest in a newly started small company in a poor country
