I think clean healthy water (and food) is a basic human need (note: priority) for every single person and every single person deserves that. Not vaccinations. Gates has poured so much money into programs to vaccinate these people, why doesnt he put it towards that instead? Because he has a vested interest and shares/ownership in companies making the vaccines.
Thats terrible, he gets to save lives and keep some of his money that he gave away. Sounds like a good deal to me!

Ouch, Yeddi! I haven't seen anyone eating dirtcakes in third world countries personally, I've seen the brown water though, I would love to know the miracle that Gates should've invested in...

In India there's a massive engineering scheme to drill wells for villages, only problem is the water table is dropping so for every well they sink another dries up. What would you do?
