Gates is yapping about symptoms of Gluttony, and is a GMO and Vaccine pusher.
Gates is a waste of wealth and space; a charity troll.
Some twits seem to be missing that much internet use in the 3rd world is by mobile, not bulky, power hungry and expensive PCs or tablets. A mobile can be cheaper, a lot more mobile, and is also a lot easier to power, especially in a sunny country.
Money is not what is important, it is availability and access to critical resources, and the knowledge of how best to use these which allow people to live, and these resources must become mostly collected or funded locally, not drip fed drug-dealer style, by effectively evil charities.
The most important resource is clean water; is there enough regularly replenished water for the current population? i.e. no drilling too many wells to progressive drain ancient aquifers until they are empty!
If there isn't; the population is too large and needs to reduce to a viable size, so just helping more people to live now without addressing resource limitations will cause far worse famine in the future!
What needs to happen is education for: better strategy, hygiene, water capture and storage, food production and storage, natural disease prevention and cures, and the plain hard truth that mothers need to limit the number of children to the available resources, rather than stupidly trying to out-breed famine mortality.
Please don't push vaccines, the science is looking increasingly dubious for these (historical hoax?) because vaccine use often trailed better hygiene, water, food, and waste disposal, thus less disease, by a significant time distance. Artificially gene spliced crops are definitely not a sensible solution either, for any country, because they are more expensive that uncorrupted crops, less productive, a more vulnerable monoculture, and often toxic!
It really is quite disgusting that people like Bill Gates can amass Billions that they can blithely spent it on 'charity' to those they think need 'pulling up'; this goes far beyond sensible reward, it is a corporatist culture of obscene resource gluttony, and bogus charity marketing.
