is that wise and possible so one person/thousands of persons can make money from internet?

I mean when one can successfully making money according to some steps, it can be replicated and shared to many people so they make money too.
The knowledge should be probably shared between friends in poverty area.

The worker need to buy computer, buy internet and that is not cheap investment..

my idea on how to earn money in which i have experience is to write articles. Write own blog (domain cost $9 yearly and hosting around $1 monthly), just read some website and then write about it, let people talk about your posts. Then monetize website. One can also write even when not having internet, and then when accumulate number of content, he can get domain, site etc..

But i wanted to ask if you have any ideas on how to make poverty areas make money from internet, how to make computer, internet investment return in earnings for anyone?
