As a developer in a third world country, I have to disagree that it is a reliable way for everyone. Not everyone has the programming skills, communication skills, confidence to reach out and negotiate for jobs above cost-of-living wages, and there is immense competition. Prospective employers will start out assuming you're not as good as programmers in the first world, you will get lowballed and the odd unscruplous employer will skip out without payment. It's a hard slog; not impossible if you're lucky enough to be born into better circumstances than others and have enough support to go the rest of the way; but definitely not something that anyone can do.
