You are sceptical that what he is doing good because it leads to overpopulation ? I think you went a little too far in trying to prove your point. I understand that any of the startups in the OP's list are not paradigm changing. And I also admit that I too would have greater appreciation for someone who would 'dig a well' - that is get dirty at the grass root level of any social movement. But this response to Bill Gate's immunization drive is either racist or social darwinism or both and I think thats wrong. Every single child born should be immunized - we as a people have solved a very basic problem of human survival and no one should be denied that. And if you are really skeptical about overpopulation how about we selectively immunize children all over the world from a lottery system ?
