So, they had to do a research study and report to discover something that anyone that has even just traveled on vacation to a "developing" country (such an euphemism) knows by just looking at the houses, streets, and more.
It is just a common sense-derived knowledge that no one can expect a person that earns less than US$500/month for a family of 5 or 6 is going to pay for software when the only thing they have to do is ask a friend to install it or copy it.
"Developing" countries are called like that precisely because more than 80% of its inhabitants earn US$2 or less a day. "First" world (or "developed") countries have a culture of abundance and shield their population from that kind of knowledge, unless you go about findig out. That's the real reason why you hace so many "cheap" goods, or why else do they assemble things such as phones, music players, clothes and about 99% of consumer goods in "thirld" world countries and not in the US or Europe?
